I would imagine it's because many people have come to recognize that both forms of data have value. I might up vote a comment that was purely anecdotal that I found interesting even if that comment was something I didn't agree with or that I felt directly conflicted with well documented research. Additionally believing that any group of people online or in person is somehow intellectually superior or immune to basic human bias is a trap that will catch you again and again. Every human- no matter how smart, educated, or well read is fallible in a multitude of ways. I feel that the incidences of this increase exponentially when you get us into a social group.
