I believe the biggest logical fallacy of our time is that correlation equals causation. A simple example of this is that most murderers are right handed. This is because most people are right handed, not because being right handed drives people to murder. There are a plethora of studies linking one thing to another, each implying that whatever their particular emphasis is significantly influences a behavior or condition. A recent example of this has been our governor's push for preschool education, citing a study showing children who attend preschool are less likely to become criminals later in life. But doesn't it make more sense that since most preschools now are private pay, the parents willing to invest in paying for preschool are also more involved in every other area of their child's development? Involved parents are less likely to raise criminals. The same argument applies to why I have noticed more overweight students in the public school choir than in the Christian school. Parents willing to sacrifice that much because they care what goes into their children's minds also care what goes into their bodies. Christian school doesn't make you slim. Here are a few other examples.
Antidepressants now come with a warning about increased risk of suicide, especially in young people. But doesn't it make more sense that since virtually all suicides are committed by depressed people, and that depressed people are more likely to be taking antidepressants, the suicides are linked to the depression, not the meds. This is especially true for young people who would be unlikely to need antidepressants for the other health conditions they are sometimes used to treat in adults.
At the 2012 primaries, a lot of Democrats voted Republican for the first time and chose fairly liberal candidates. This fueled theories that the Democrats were conspiring to get bad Republican candidates on the November ballot. But doesn't it make more sense that Democrats, unhappy with their party over Obamacare cramming, voted for Republicans most like the Democrats they had previously chosen.
If you search the internet, you will find studies linking being overweight and/or diabetes to consumption of french fries/soda/wheat/doughnuts/you name it. But doesn't it make more sense that these things are single elements of a generally unhealthy lifestyle rather than causes themselves.
Between the general misunderstanding of the relationship of correlation versus cause, the biases of study sponsors and/or those of the researchers themselves, the information age has become the misinformation age, of which sloppy journalism is just one of the signs. I don't have studies to verify my conclusions, but doesn't it just make sense?
