Reviewing the science behind the potential benefits of fidgeting may make you fidget, because there are theories but limited concrete scientific evidence. One thought is that fidgeting may occupy parts of your brain that otherwise would distract the rest of your brain with random thoughts. Imagine that your brain is a family that needs to make an important decision. If the young children in the family aren’t occupied by toys, they may demand too much attention, interfering with decision making.
