Be careful what you write, you watch

You have always been part of the statistics. Of low or high, of those who buy or not. Now that you manifest in your network, you write on Twitter or Facebook, many organizations know more about you. Automatic systems begin to draw conclusions from your trail on the network. As a new study in which psychopathic tendency correlates with certain features of Twitter.

An analysis of how you write on Twitter can reveal if you're narcissistic, Machiavellian or psychopathic, according to a recent survey . Some of the defining features are: curses, angry responses to other people including insults and the word "hate", the use of the word "we" instead of "I", the use of points or the use of words, such as blah, blah or ummm.

The study's author, Chris Sumner thinks

The FBI can use to signal to potential offenders, but I think it is more useful for psychologists to use it to understand the large groups of people

The study is a response to a similar one called "Hungry like a wolf: an analysis of patterns of words in the language of psychopaths."

The study was conducted with almost 3000 participants who scored themselves in the so-called Dark Triad: Narcissism, Machiavellianism and psychopathy. The results showed a number of significant correlations between the personality of the individual dark and activity on Twitter. The study used a machine learning model to be improving predictions. Activity at Twitter was translated into numbers, namely 337 points showing the frequency number of tweets or linguistic features among others. The data fueled a data model that was exploited with datawarehouse techniques or Big Data .

How far can this analysis? Sumner himself is reluctant. Technically there is the problem of false positives, people who appear as though they are not psychopaths. And in general, move from general studies to particular cases is scientifically dubious, as well as morally problematic, and privacy.

I scored high just because someone does not mean it is a criminal. Use this to try to locate someone who will commit an offense will result in catching people who are not going to do it. But in general is interesting. It can be used to see large groups of people and ask whether we are becoming more antisocial.

We passed a world where privacy is scarce and we have stripped to the public. What I write on the network can remain there for many years. Some behaviors are highly recommended. It is the case of the writer: "Tomorrow I have an interview for a job in a company awful awful" and it turns out that the interviewer has read the message. However, everyone is entitled to be a troll but why police pursued him. The debate is open: every day we are free, but the guards do not rest automatic.
