Evolution & Rationality- Brandon

This week’s lecture started off unexpected. Professor Bloom spent the first twenty minutes or so talking about evolution. He compared it with creationism and showed why it was the more logical explanation for how we came to be. He basically just reiterated points that I had learned in biology last year so it wasn’t that helpful. I got more interested in the lecture when the professor talked about how evolution relates to psychology and our understanding of the brain. 

Evolution is relevant because it shows us what is innate and what is not. It also shows us the diversity and differences in our minds. Most of all,  “Looking at something from the
perspective of design often leads to interesting insights about its current nature”(Bloom). My favorite part of the evolution discussion was when Professor Bloom segued to the topic of rationality.

I always saw rationality as pure logic and never questioned evolution’s role. The brain’s natural tendency of incest avoidance is a perfect example of how evolution affected our brains. Beyond that, Professor Bloom talked about the many biases in our brain.  The one I found the most applicable to day to day life was confirmation bias. In simple terms, our brain looks for things that confirm the opinions we already have. We are more likely to seek out sources or people with viewpoints that line up with ours. That’s why you rarely see hardcore Republicans watching MSNBC and hardcore Democrats watching Fox News. Our brain wants to tune out things that we don’t agree with.

Overall, this lecture had a few highlights but it was not one of my favorites. I found myself getting bored at times but I’m looking forward to next week’s course on emotion. Sorry for the short post, I did not take many notes because I felt a bit uninspired.

    I’d have to say that your bit about seeking out people who’s interests and beliefs align with ours is undeniably true. Just a few weeks ago, when speaking with the Israeli settler Ardy, I felt truly disturbed and disgusted by the passerby comments flying from his mouth. Then, nearly a week later, when talking to Jean Z, whose opinions aligned perfectly with my own, I felt totally at home and happy. So yeah, I’d say that theory is nearly fact in my book. Thanks for the well-written post!

    I like some information you posted about logic. It is sure very important and explains how our brain works. The biases are interesting and I hope I can learn more. I’m looking forward to your next post.
