Hard liquor is absorbed faster than beer which leads to a stronger rush effect. It's similar to snorting vs shooting cocaine. When the effect hits faster, the psychological association between the stimuli and the effect (sensitization) becomes stronger.

This effect has been demonstrated with rat studies using cocaine:

Why would liquor be absorbed faster than beer given the same route (drinking)?

		Fick’s Law. The rate of absorption is proportional to the concentration gradient.

		It's easier to drink more units of alcohol faster when it's more concentrated, and not full of bubbles. I don't think its so much that it's absorbed faster than it's just physically possible to drink 200 ml of liquor faster than it is to drink 1600ml of beer.
