SB: i dun think its common sense or not la..maybe in bio yes,
but intelligence is one of the more focused topics in psych, so its
not really common sense here..
btw cool:
heredity: inborn characteristics inherited from the iological
parents at conception
heritablility: stats. estimate of contribution of heredity to
individual difference in specific trait within a given
population.
defn taken from text..this should give u a better idea...
tat e.g. i gave u jus now is trying to say that e difference btw u
n ur friends intellgence, is cos of 60% is from ur parents..hence e
variation tatz mention in the notes
