Submission + - Twitter Can Identify Heart Disease (i-programmer.info)
mikejuk writes: Researchers have shown that Twitter can serve as a dashboard indicator of a community’s psychological well-being and can predict rates of heart disease. Many factors contribute to the risk of heart disease, not just traditional ones, like low income or smoking but also psychological ones, like stress. The team found that negative emotional language and topics, such as words like “hate” or expletives, remained strongly correlated with heart disease mortality, even after variables like income and education were taken into account. Positive emotional language showed the opposite correlation, suggesting that optimism and positive experiences, words like “wonderful” or “friends,” may be protective against heart disease.
The maps produced showing heart disease rates according to Twitter show a remarkable match to maps of actual death due to heart disease.
As one team member commented:
“The relationship between language and mortality is particularly surprising since the people tweeting angry words and topics are in general not the ones dying of heart disease. But that means if many of your neighbors are angry, you are more likely to die of heart disease.”
