The following article deals with how comments impact a persons belief depending on the tone of “troll” comments in regards to science. I would venture to guess the study the article references could probably be applied to other aspects of life especially politics.

Comments have a way to entrench people in their emotions. And this past presidential election had more than enough troll comments. I find it fascinating to read the comments on political topics. Next time you read comments on the internet how long the thread last until Godwin’s Law of Nazi Analogies occurs. If you aren’t familiar with that law or rule it’s simply “As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one.”
