You are testing whether people who switch between languages are better multitasks. You find no correlation, but upon close inspection of the data, you realize that people who never and frequently switch between languages are not good at multitasking, but people who switch only sometimes are very good. In other words, people at the extreme ends of the scale do poorly, while those in the middle of the scale do well
