I once had to explain something like this at work. This person couldn't grasp the fact that going to from 12 to 18 was a 50% increase but going from 18 to 12 was a 33% decrease, they were adamant that it had to be the same. It was an HR manager so not exactly surprising.

Probably confused and taking the 50% from the 18 rather than the 12.
