Government of Ireland Report Features Research by Scott M. Graffius
10 June 2026
BY SCOTT M. GRAFFIUS | ScottGraffius.com
Rialtas na hÉireann (Government of Ireland) Coimisiún na Meán is the county's commission for regulating broadcasters, on-demand services, and online media, and for supporting media development. Established in March 2023 under the Online Safety and Media Regulation Act 2022, it builds on the work of its predecessor, the Broadcasting Authority of Ireland. The commission is responsible for ensuring and maintaining a thriving and diverse media landscape that facilitates a mix of voices, opinions, and sources of information — and, critically, for holding digital services accountable for how they protect people from harm online.
One of Coimisiún na Meán's initiatives is the Online Safety Code. It's Ireland's first binding regulatory framework for video-sharing platform services. The Code sets out measures that designated platforms are legally obliged to implement to protect users from harmful content, including cyberbullying, content that promotes eating disorders or self-harm, and inappropriate material accessible to minors. The development of the Code involved extensive public consultation, commissioned research, and expert review.
As part of that process, Coimisiún na Meán commissioned Wagner-Hatfield to prepare a summary of the responses received during the public consultation on the draft Online Safety Code. The resulting report — Consultation Responses to the Draft Online Safety Code — synthesizes the submissions received from the public, government departments and agencies, NGOs, civil society organizations, industry groups, international regulators, and academia. It represents a component of the evidentiary record that informed the finalized Code.
The Consultation Responses report cited Scott M. Graffius' "Lifespan (Half-Life) of Social Media Posts" research. The report includes the following passage in Section 4C.9 (page 64):
"The results of a 2023 empirical investigation which determined the lifespan of social media posts on different platforms was shared which showed: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo).37"
That's immediately followed by, "A lower lifespan means that most harm happens right after the content is posted, which shows that content moderation needs to be performed quickly to be effective."
The respective content is also shown in the visual below.
Although the Consultation Responses report cites Graffius' research, it materially mischaracterizes it — and compounds the inaccuracy by drawing a conclusion that does not follow from the cited work.
Citations can readily create an impression of alignment or endorsement where none exists, particularly for readers who do not scrutinize the underlying research in detail. Given the regulatory weight of the Online Safety Code — a binding law applied to designated platforms, with fines of up to €20 million for breaches — errors in the evidentiary record that informs it carry real consequences.
To maintain the integrity of his work and prevent misunderstanding, Graffius proactively provides the following objective, evidence-based assessment of the Consultation Responses report, including its use of his research.
Graffius does not endorse the Consultation Responses report.
1. Mischaracterization of the Metric: Half-Life Is Not Lifespan.
In social media research and digital analytics, half-life and lifespan are distinct concepts that serve different analytical purposes. Lifespan, in its ordinary sense, implies a general duration — how long a post exists, circulates, or remains accessible. Half-life is a precise statistical construct with a specific definition: the point at which a post has received half of its total engagement (such as likes, shares, and comments).
Graffius defined this metric explicitly in his research: "The lifespan of posts is of interest, and a helpful metric is half-life. It's the amount of time it takes for a post to receive half of its total engagement (such as likes, shares, and comments)."
The reason half-life is the operative and appropriate metric — rather than a general notion of lifespan — stems from how engagement is distributed over the life of a social media post. When content is published, engagement does not follow a symmetrical bell curve. Instead, it follows a unimodal, positively skewed distribution: the majority of engagement arrives relatively soon after posting, with the remainder spread across a comparatively longer tail. Because engagement is front-loaded in this way, half-life is the most meaningful and actionable metric for characterizing post longevity. It captures a precise, reproducible, and operationally useful threshold.
The Consultation Responses report substitutes "lifespan" for "half-life," misrepresenting what the research measures. This is not a minor editorial inconsistency. It misidentifies the metric, obscures the statistical basis of the findings, and undermines the accuracy of any interpretation or policy conclusion that depends on the cited data.
Graffius' research, built on a large dataset from multiple sources, reveals the average half-life for posts on different social media platforms. The data in the cited (2023) edition showed: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo). Findings from others — including anecdotal experience from select posts or limited datasets — may vary from these averages, which reflect a large, multi-source, representative methodology.
The Consultation Responses report cited the 2023 edition of Graffius' "Lifespan (Half-Life) of Social Media Posts." For context, a visual from it is shown below.
Details—including a link to it, the Consultation Responses report, and more—are in the bibliography section of this article.
Additionally, because this article is written in 2026, a visual from the current (2026) edition of Graffius’ respective work is also provided below for completeness and contemporaneous context. The 2026 edition stands out for its:
◾️ Scope (5.6 million posts),
◾️ Coverage (11 platforms),
◾️ Methodology (multi-source, representative, data-driven),
◾️ Continuity (annual updates), and
◾️ Value (actionable insights).
2. Unsupported Causal Claim: Half-Life of Engagement Does Not Establish When Harm Occurs.
The report states: "A lower lifespan means that most harm happens right after the content is posted, which shows that content moderation needs to be performed quickly to be effective."
That conclusion does not follow from the cited research. Graffius' work measures the half-life of engagement — when a post receives half of its total interaction from users. It does not measure when harm occurs, nor does it establish any causal or correlational relationship between engagement timing and harm timing.
Engagement and harm are not equivalent. A post may generate limited engagement and still cause significant harm (as defined by the legislation). Conversely, a high-engagement post may be broadly benign. Harm can also manifest well after a post's engagement peak — through screenshots, redistribution, offline consequences, or discovery by new audiences on other platforms. The half-life of engagement provides no basis for making direct inferences about the timing or distribution of harm.
By asserting that "most harm happens right after the content is posted" and attributing that conclusion to empirical research on engagement half-life, the Consultation Responses report draws an inference that the data do not support. The policy recommendation is not substantiated by the cited work as applied in the report.
3. Regulatory Consequences of Analytical Errors.
The Consultation Responses report is not an academic exercise. It is part of the evidentiary record underlying the Online Safety Code — Ireland's first binding regulatory framework for video-sharing platforms, with designated enforcement powers and fines of up to €20 million for breaches. Platforms subject to the Code must implement content moderation measures, and the timing, scope, and design of those measures are precisely the questions at issue in the passage that cites Graffius' research.
When the analytical basis for a regulatory finding is flawed — whether through mischaracterization of a metric or an unsupported causal inference — the practical consequences extend to real compliance obligations imposed on real organizations. Erroneous findings do not simply sit on a page; they propagate into policy design, enforcement priorities, and the design of moderation systems. The stakes are high enough to warrant a precise and accurate account of what the cited research shows.
Graffius suggests that the passage in Section 4C.9 be corrected to reflect both the accurate metric and a conclusion that the data support. The current passage is:
"The results of a 2023 empirical investigation which determined the lifespan of social media posts on different platforms was shared which showed: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo).37 A lower lifespan means that most harm happens right after the content is posted, which shows that content moderation needs to be performed quickly to be effective."
It should be corrected to the following (or similar):
"The results of a 2023 empirical investigation determined the average half-life of posts on different social media platforms. Half-life is the point at which a post has received half of its total engagement (such as likes, shares, and comments). The research showed the following half-life durations: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo).37 [The lower the half-life, the sooner a post accumulates 50% of its total engagement, narrowing the window in which content moderation—if required—can reduce its reach and impact.]"
The Consultation Responses report exhibits significant issues, including:
Given that the Consultation Responses report forms part of the evidentiary record underlying binding regulatory obligations, these deficiencies matter beyond the page. Accordingly, the report's specific findings and conclusions regarding social media post lifespan and content moderation timing should be treated with caution.
"May 2024" appears on the Consultant Responses report, and metadata for the PDF shows the modify date of May 20, 2024. Graffius was alerted to the report on June 1, 2024. That day, Graffius notified multiple parties involved with the report about the issues with it. He emailed (email addresses redacted) the Coimisiún na Meán (███████████@cnam.ie and ████@cnam.ie), Wagner-Hatfield (████@wagner- hatfield.com, ███@wagner-hatfield.com, and ███@wagner-hatfield.com), and DHR (███████████████@dhr.ie). None has responded to date. After providing the involved parties with an opportunity to address the issues and receiving no response, Graffius is presenting the details in this article to preserve the accuracy and integrity of the record.
Graffius' "Lifespan (Half-Life) of Social Media Posts" research has been correctly used by many businesses, professional associations, government agencies, universities, publications, media outlets, and others worldwide. Select examples include:

Government of Ireland, Commission for Media, Wagner-Hatfield, the Consultation Responses to the Draft Online Safety Code Report, and Its Use of Graffius' Research
Rialtas na hÉireann (Government of Ireland) Coimisiún na Meán is the county's commission for regulating broadcasters, on-demand services, and online media, and for supporting media development. Established in March 2023 under the Online Safety and Media Regulation Act 2022, it builds on the work of its predecessor, the Broadcasting Authority of Ireland. The commission is responsible for ensuring and maintaining a thriving and diverse media landscape that facilitates a mix of voices, opinions, and sources of information — and, critically, for holding digital services accountable for how they protect people from harm online.
One of Coimisiún na Meán's initiatives is the Online Safety Code. It's Ireland's first binding regulatory framework for video-sharing platform services. The Code sets out measures that designated platforms are legally obliged to implement to protect users from harmful content, including cyberbullying, content that promotes eating disorders or self-harm, and inappropriate material accessible to minors. The development of the Code involved extensive public consultation, commissioned research, and expert review.
As part of that process, Coimisiún na Meán commissioned Wagner-Hatfield to prepare a summary of the responses received during the public consultation on the draft Online Safety Code. The resulting report — Consultation Responses to the Draft Online Safety Code — synthesizes the submissions received from the public, government departments and agencies, NGOs, civil society organizations, industry groups, international regulators, and academia. It represents a component of the evidentiary record that informed the finalized Code.
The Consultation Responses report cited Scott M. Graffius' "Lifespan (Half-Life) of Social Media Posts" research. The report includes the following passage in Section 4C.9 (page 64):
"The results of a 2023 empirical investigation which determined the lifespan of social media posts on different platforms was shared which showed: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo).37"
That's immediately followed by, "A lower lifespan means that most harm happens right after the content is posted, which shows that content moderation needs to be performed quickly to be effective."
The respective content is also shown in the visual below.
Although the Consultation Responses report cites Graffius' research, it materially mischaracterizes it — and compounds the inaccuracy by drawing a conclusion that does not follow from the cited work.

To maintain the integrity of his work and prevent misunderstanding, Graffius proactively provides the following objective, evidence-based assessment of the Consultation Responses report, including its use of his research.
Graffius does not endorse the Consultation Responses report.
Critical Analysis of the Consultation Responses Report, Including Its Use of Graffius' Research
1. Mischaracterization of the Metric: Half-Life Is Not Lifespan.
In social media research and digital analytics, half-life and lifespan are distinct concepts that serve different analytical purposes. Lifespan, in its ordinary sense, implies a general duration — how long a post exists, circulates, or remains accessible. Half-life is a precise statistical construct with a specific definition: the point at which a post has received half of its total engagement (such as likes, shares, and comments).
Graffius defined this metric explicitly in his research: "The lifespan of posts is of interest, and a helpful metric is half-life. It's the amount of time it takes for a post to receive half of its total engagement (such as likes, shares, and comments)."
The reason half-life is the operative and appropriate metric — rather than a general notion of lifespan — stems from how engagement is distributed over the life of a social media post. When content is published, engagement does not follow a symmetrical bell curve. Instead, it follows a unimodal, positively skewed distribution: the majority of engagement arrives relatively soon after posting, with the remainder spread across a comparatively longer tail. Because engagement is front-loaded in this way, half-life is the most meaningful and actionable metric for characterizing post longevity. It captures a precise, reproducible, and operationally useful threshold.
The Consultation Responses report substitutes "lifespan" for "half-life," misrepresenting what the research measures. This is not a minor editorial inconsistency. It misidentifies the metric, obscures the statistical basis of the findings, and undermines the accuracy of any interpretation or policy conclusion that depends on the cited data.
Graffius' research, built on a large dataset from multiple sources, reveals the average half-life for posts on different social media platforms. The data in the cited (2023) edition showed: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo). Findings from others — including anecdotal experience from select posts or limited datasets — may vary from these averages, which reflect a large, multi-source, representative methodology.
The Consultation Responses report cited the 2023 edition of Graffius' "Lifespan (Half-Life) of Social Media Posts." For context, a visual from it is shown below.
Details—including a link to it, the Consultation Responses report, and more—are in the bibliography section of this article.
Additionally, because this article is written in 2026, a visual from the current (2026) edition of Graffius’ respective work is also provided below for completeness and contemporaneous context. The 2026 edition stands out for its:
◾️ Scope (5.6 million posts),
◾️ Coverage (11 platforms),
◾️ Methodology (multi-source, representative, data-driven),
◾️ Continuity (annual updates), and
◾️ Value (actionable insights).
2. Unsupported Causal Claim: Half-Life of Engagement Does Not Establish When Harm Occurs.
The report states: "A lower lifespan means that most harm happens right after the content is posted, which shows that content moderation needs to be performed quickly to be effective."
That conclusion does not follow from the cited research. Graffius' work measures the half-life of engagement — when a post receives half of its total interaction from users. It does not measure when harm occurs, nor does it establish any causal or correlational relationship between engagement timing and harm timing.
Engagement and harm are not equivalent. A post may generate limited engagement and still cause significant harm (as defined by the legislation). Conversely, a high-engagement post may be broadly benign. Harm can also manifest well after a post's engagement peak — through screenshots, redistribution, offline consequences, or discovery by new audiences on other platforms. The half-life of engagement provides no basis for making direct inferences about the timing or distribution of harm.
By asserting that "most harm happens right after the content is posted" and attributing that conclusion to empirical research on engagement half-life, the Consultation Responses report draws an inference that the data do not support. The policy recommendation is not substantiated by the cited work as applied in the report.
3. Regulatory Consequences of Analytical Errors.
The Consultation Responses report is not an academic exercise. It is part of the evidentiary record underlying the Online Safety Code — Ireland's first binding regulatory framework for video-sharing platforms, with designated enforcement powers and fines of up to €20 million for breaches. Platforms subject to the Code must implement content moderation measures, and the timing, scope, and design of those measures are precisely the questions at issue in the passage that cites Graffius' research.
When the analytical basis for a regulatory finding is flawed — whether through mischaracterization of a metric or an unsupported causal inference — the practical consequences extend to real compliance obligations imposed on real organizations. Erroneous findings do not simply sit on a page; they propagate into policy design, enforcement priorities, and the design of moderation systems. The stakes are high enough to warrant a precise and accurate account of what the cited research shows.
Suggested Corrections to Consultation Responses Report
Graffius suggests that the passage in Section 4C.9 be corrected to reflect both the accurate metric and a conclusion that the data support. The current passage is:
"The results of a 2023 empirical investigation which determined the lifespan of social media posts on different platforms was shared which showed: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo).37 A lower lifespan means that most harm happens right after the content is posted, which shows that content moderation needs to be performed quickly to be effective."
It should be corrected to the following (or similar):
"The results of a 2023 empirical investigation determined the average half-life of posts on different social media platforms. Half-life is the point at which a post has received half of its total engagement (such as likes, shares, and comments). The research showed the following half-life durations: Snapchat (0 min), Twitter (24 min), Facebook (105 min), Instagram (20 h), LinkedIn (24 h), YouTube (8.8 d), and Pinterest (3.75 mo).37 [The lower the half-life, the sooner a post accumulates 50% of its total engagement, narrowing the window in which content moderation—if required—can reduce its reach and impact.]"
Conclusion
The Consultation Responses report exhibits significant issues, including:
- A material mischaracterization of the cited metric (half-life vs. lifespan); and
- An unsupported causal inference that conflates engagement timing with harm timing, producing a conclusion that the cited data do not substantiate.
Given that the Consultation Responses report forms part of the evidentiary record underlying binding regulatory obligations, these deficiencies matter beyond the page. Accordingly, the report's specific findings and conclusions regarding social media post lifespan and content moderation timing should be treated with caution.
"May 2024" appears on the Consultant Responses report, and metadata for the PDF shows the modify date of May 20, 2024. Graffius was alerted to the report on June 1, 2024. That day, Graffius notified multiple parties involved with the report about the issues with it. He emailed (email addresses redacted) the Coimisiún na Meán (███████████@cnam.ie and ████@cnam.ie), Wagner-Hatfield (████@wagner- hatfield.com, ███@wagner-hatfield.com, and ███@wagner-hatfield.com), and DHR (███████████████@dhr.ie). None has responded to date. After providing the involved parties with an opportunity to address the issues and receiving no response, Graffius is presenting the details in this article to preserve the accuracy and integrity of the record.
Graffius' "Lifespan (Half-Life) of Social Media Posts" research has been correctly used by many businesses, professional associations, government agencies, universities, publications, media outlets, and others worldwide. Select examples include:
- BCG,
- École Polytechnique Fédérale de Lausanne,
