An increase in the degree a good is liked (the increase in the taste for a good) would

Increase demand

Explanation:

Tastes and preferences of the consumers is one of the determinant of demand that would shift the demand curve rightwards or leftwards.

Now, if there is an increase in the taste of the consumers for a good then as a result this would increase the market demand for that particular good. This would also shifts the demand curve of that good rightwards.

If there is a positive change in the taste of the consumers for a good then they will buy more quantity of that good.
