Study: When Trump tweets about Muslims, hate crimes increase
"We find that Trump’s anti-Muslim tweets are highly correlated with the number of anti-Muslim hate crimes, particularly where Twitter usage is high, but only after the start of his presidential campaign."
It’s not your imagination, folks. An increase in hate speech on social media—and especially, Twitter—is leading to increased hate crimes and violence away from social media.
The study, published in Social Science Research Network, focuses specifically on anti-Muslim hate speech and violence in the Trump era. There’s a strong correlation between accounts with high numbers of followers (such as the president of the United States) tweeting hate speech and racist remarks, and follow-up violence and hatred in public and even in private settings. In other words, offline.
"Weekly Hate Crimes in the United States since 1990, by President: This figure plots the average weekly number of hate crimes, by president. Panel (a) shows the full period of the presidency. Panel (b) shows the bar graphs for the identical end-of-year periods after the election. The bars indicate the 95% confidence intervals. The triangle marks the median."

This doesn’t just happen in the United States, but all over the world. In fact, one rather chilling observation from a previous study by Karsten Müller and Carlo Schwarz is that in parts of the world that suffer an Internet outage, the actions of hate and violence actually decreased during that time. Major Internet and Facebook outages "fully undo the correlation between social media and hate crime."
Müller and Schwarz's latest 30-page paper is based on publicly available documents recorded by law enforcement and the FBI.
Monthly Hate Crimes by Twitter Usage: This figure plots the monthly number of anti-Muslim hate crimes per capita for counties above and below the 90th percentile of Twitter usage. The vertical line marks the beginning of Trump’s presidential campaign. (Source: Karsten Muller and Carlo Schwarz)
In the abstract for the study, the authors postulate: “We show that the rise in anti-Muslim hate crimes since Donald Trump's presidential campaign has been concentrated in counties with high Twitter usage. Consistent with a role for social media, Trump's tweets on Islam-related topics are highly correlated with anti-Muslim hate crime after, but not before the start of his presidential campaign, and are uncorrelated with other types of hate crimes. These patterns stand out in historical comparison: Counties with many Twitter users today did not consistently experience more anti-Muslim hate crimes during previous presidencies.”
The correlation holds when certain keywords are used—for example, when hashtags or keywords such as 'Islam' or 'Muslim' are used by the president in a tweet. It's also quite clear that in counties with a higher number of Twitter users, the hate crimes against Muslims are correspondingly higher after the original tweets go out.
Interestingly, there is no correlation between counties that are poorer or those that have higher crime rates and those with a higher percentage of anti-Muslim hate crimes.
It appears that social media—and more exactly, Twitter—is what is amplifying the problem.
So... what to do about that?
What would it be like to experience the 4th dimension?
Physicists have understood at least theoretically, that there may be higher dimensions, besides our normal three. The first clue came in 1905 when Einstein developed his theory of special relativity. Of course, by dimensions we’re talking about length, width, and height. Generally speaking, when we talk about a fourth dimension, it’s considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.
If machines develop consciousness, or if we manage to give it to them, the human-robot dynamic will forever be different.
- Does AI—and, more specifically, conscious AI—deserve moral rights? In this thought exploration, evolutionary biologist Richard Dawkins, ethics and tech professor Joanna Bryson, philosopher and cognitive scientist Susan Schneider, physicist Max Tegmark, philosopher Peter Singer, and bioethicist Glenn Cohen all weigh in on the question of AI rights.
- Given the grave tragedy of slavery throughout human history, philosophers and technologists must answer this question ahead of technological development to avoid humanity creating a slave class of conscious beings.
- One potential safeguard against that? Regulation. Once we define the context in which AI requires rights, the simplest solution may be to not build that thing.
Duke University researchers might have solved a half-century old problem.
- Duke University researchers created a hydrogel that appears to be as strong and flexible as human cartilage.
- The blend of three polymers provides enough flexibility and durability to mimic the knee.
- The next step is to test this hydrogel in sheep; human use can take at least three years.
Duke researchers have developed the first gel-based synthetic cartilage with the strength of the real thing. A quarter-sized disc of the material can withstand the weight of a 100-pound kettlebell without tearing or losing its shape.
