I also see a trend that people look for correlations, find correlations and then draw some conclusion without any proof of causation. To me it strikes me most for economics. Public policy is set based on those correlations.
It is very counterintuÃtive but correlation research means nothing, especially in economics. Correlation research would be an amusing way to spend your time and get to know some variables, but correlation research is being used to inflence people. Repeat after me: correlation means nothing. If you find a correlation luck has hit you. Or luck has been manipulated to serve some point. Correlation means nothing whatsoever. Articles describing correlation are a waist of your time. You should not act based on correlation research.
Now if you take big datasets with lots of variables and you test correlations between those variables, you will find strong correlations. Correlation here, correlation there, correlation everywhere. If you do millions of tests en tweak your parameters, correlation is all yours.
But luckily now you know: correlation has no pratical use in your live.
