It does make sense, If you took a really smart academic whos previous friends at sixth form would of also been smart academic students and put them in a crowd of possibly smart, but out going
partying students they wont get along. Now is that person a bigot for not really wanting to socialise with people that are different to them.
Same thing applys with if you took an outgoing party person and stuck them in a crowd of smart academics they too would not get along.
