Other forms: proclivities
A proclivity is a natural leaning towards a way of behaving. A proclivity for risk, criminal proclivities, a proclivity towards it.
It is nearly always used of something unwelcome, which is what separates it from talent or aptitude. The Latin means sloping forward, so a proclivity is a tilt in one direction.
