I'm a 17 year old High School senior. I discovered Less Wrong through the author page at HP:MoR. I had considered myself a rational person for some time, but the Sequences here have really opened my eyes to the glaring errors I was making as a Traditional Rationalist. Consequently, this site has already changed my life for the better and I really just want to thank all the main contributors here. Thank You!
Also, I am looking to Major in Cognitive Science in college and any suggestions as to good schools to apply would be appreciated, along with any advice as to reading or preparation I should do before entering this field.
Welcome to less wrong! I don't know enough about you to predict where you could be accepted, but MIT and Caltech are both great schools for anyone who wants to study Cognitive Science.
