Why it Always is Important to Study, Analyze, Think: Humans are Subjective

As sometimes is the case, a study suggests what most people commonly assume--that a politician in a crowded field can gain momentum, changing voter preferences--is not something actual voting patterns can validate. 

This arguably is an issue for many of the instances where people (voters or officials) support policies to achieve some public policy end. Maybe we do not have the causal relationships understood; maybe they are too complex to be understood; maybe the correlations are produced by something we are not capable of quantifying. 

Some might argue such fogginess applies in economic and busines life as well.
