An interesting paper tested project bias/how people over-predicted the degree to which their future tastes will resemble one's current tastes ("never shop on an empty stomach!").
"We find that the choice to purchase a convertible, a 4-wheel drive, or a
vehicle that is black in color is highly dependent on the weather at
the time of purchase in a way that is inconsistent with classical
utility theory. Similarly, we find that the hedonic value that a
swimming pool and that central air add to a house is higher when the
house goes under contract in the summertime compared to the wintertime."
