Personality and Genetics

last semester, i took a course for which i had to read tim LaHaye’s book about temperaments. of course, if you don’t agree with time LaHaye on some things, this book really wasn’t based on his theory. it was about sanguine, choleric, phlegmatic, and melancholy temperaments. it said genes determine what temperament a person will have. so, that makes me wonder… will it ever be possible to adjust people’s personalities/personality disorders through genetic engineering?
