People who casually like or retweet activist content on social media are often criticized as "slacktivists." But in analyzing millions of tweets surrounding social protests, Professor Sandra González-Bailón and her co-authors find that in fact, these peripheral users serve to double the reach of the core protesters' message.
This presentation by Annenberg Professor Damon Centola, "The Spontaneous Emergence of Conventions: An Experimental Study of Cultural Evolution," explores social conventions and how they form.
Why do we continue to make unhealthy and even dangerous choices, such as smoking, when these behaviors are changeable?
Determining what makes people do things differently is a daunting challenge. Professor Emily Falk’s research unites brain imaging and behavioral outcomes to discover the messages that work to help people help themselves.
In a new study led by Professor Emily Falk, brain scans of 50 smokers in Michigan were able to help predict the results of an email campaign sent to 800,000 in New York, demonstrating the promise of neuroscience to inform and improve public health campaigns.
A new study by Professor Damon Centola, along with graduate students Jingweng Zhang, Devon Brackbill, and Sijia Yang showed that the social influence of online peers can be more effective than traditional motivational messaging in encouraging physical activity.
