It is because the human brain tends to be wired in a certain way. One guy says something and other people begin to reflect on what he has said.

Some times, when reading blog posts like these, I wonder if the point of the post is to disagree for the sole purpose of driving traffic and gossip. The problem is not that these people publish. The problem rather is that they get upvoted on a site like this one. The article lacks a number of compelling arguments as to why his viewpoint is true. On the contrary, Grahams article backs the statements up by history.
