HMN 2025: How Some politicians who share dangerous info are rewarded with extra clicks,

What occurs when politicians submit false or poisonous messages on-line? My crew and I discovered proof that implies U.S. state legislators can increase or decrease their public visibility by sharing unverified claims or utilizing uncivil language throughout instances of excessive political rigidity. This raises questions on how social media platforms form public opinion and, deliberately or not, reward sure behaviors.

I’m a computational social scientist, and my crew builds instruments to check political communication on social media. In our newest study we checked out what forms of messages made U.S. state legislators stand out on-line throughout 2020 and 2021—a time marked by the pandemic, the 2020 election and the Jan. 6 Capitol riot. We centered on two forms of dangerous content material: low-credibility info and uncivil language comparable to insults or excessive statements. We measured their influence primarily based on how extensively a submit was preferred, shared or commented on on Facebook and X, on the time Twitter.

Our study discovered that this dangerous content material is linked to increased visibility for posters. However, the consequences differ. For instance, Republican legislators who posted low-credibility info had been extra prone to obtain larger on-line consideration, a sample not noticed amongst Democrats. In distinction, posting uncivil content material usually decreased visibility, notably for lawmakers at ideological extremes.

Why it issues

Social media platforms comparable to Facebook and X have turn into one of many main stages for political debate and persuasion. Politicians use them to succeed in voters, promote their agendas, rally supporters and assault rivals. But a few of their posts get way more consideration than others.

Earlier analysis confirmed that false info spreads faster and reaches wider audiences than factual content material. Platform algorithms typically push content material that makes individuals indignant or emotional higher in feeds. At the identical time, uncivil language can deepen divisions and make individuals lose trust in democratic processes.

When platforms reward dangerous content material with elevated visibility, politicians have an incentive to submit such messages, as a result of elevated visibility can lead on to larger media consideration and probably extra voter help. Our findings elevate issues that platform algorithms might unintentionally reward divisive or deceptive conduct.

When dangerous content material turns into a successful technique for politicians to face out, it might probably distort public debates, deepen polarization and make it tougher for voters to search out trustworthy information.

How we did our work

We gathered almost 4 million tweets and half 1,000,000 Facebook posts from over 6,500 U.S. state legislators throughout 2020 and 2021. We used machine {learning} strategies to find out causal relationships between content material and visibility.

The strategies allowed us to match posts that had been comparable in virtually each facet besides that one had dangerous content material and the opposite did not. By measuring the distinction in how extensively these posts had been seen or shared, we might estimate how a lot visibility was gained or misplaced due solely to that dangerous content material.

What different analysis is being finished

Most analysis on dangerous content material has centered on nationwide figures or social media influencers. Our study as a substitute examined state legislators, who considerably form state-level legal guidelines on points comparable to schooling, well being and public security however sometimes obtain much less media coverage and fact-checking.

State legislators typically escape broad scrutiny, which creates alternatives for misinformation and poisonous content material to unfold unchecked. This makes their on-line actions particularly necessary to know.

What’s subsequent

We plan on conducting ongoing analyses to find out whether or not the patterns we discovered through the intense years of 2020 and 2021 persist over time. Do platforms and audiences proceed rewarding low-credibility info, or is that impact non permanent?

We additionally plan to look at how modifications sparsely insurance policies comparable to X’s shift to less oversight or Facebook’s end of human fact-checking have an effect on what will get seen and shared. Finally, we wish to higher perceive how individuals react to dangerous posts: Are they liking them, sharing them in outrage, or attempting to right them?

Building on our present findings, this line of analysis can assist form smarter platform design, more practical digital literacy efforts and stronger protections for wholesome political dialog.
