It’s no secret that the information we share on social media can get us in trouble. You can embarrass yourself, ruin your reputation, and even get arrested using fewer than 140 characters.
Tweets are also reflections of a person’s current state – they shed light on things we find interesting, the events in our lives, and our opinions. In these cases, we’re conscious of the states our tweets reflect. However, our tweets may also be able to predict aspects of our lives that we’re not conscious of at the time of tweet composition, like the rate of heart attacks in the communities we live in.
If you think about it, it’s not that surprising that negative tweets come from places with greater incidences of cardiac events. The authors crucially point out that it was not the tweeters who were dying, though. One person’s angry tweets did not predict that same person’s later risk of heart attack (though to me this doesn’t seem like too far-fetched a possibility). Instead, the counties that the most negative tweets were coming from were the same ones that had the highest incidence of cardiac events. I don’t think anyone would argue that the angry tweets (coming primarily from young people) were causing high rates of heart attack (in primarily old people). Instead, the correlation probably reflects that good physical and mental health are often associated – both in individuals and on a larger geographical level. So what should we do with this knowledge? Is there anything we can do beyond existing efforts to improve heath and wellness in the communities that need it most? What other warning signs are evident in corpora containing millions of tweets and other social media behaviors?
I don’t know. I’m about to go tweet about rainbows and daisies though, just in case.
