Possibly, it depends on the individual cop. However, I think the idea is that if you haven’t done anything wrong and you don’t answer any questions you’re in a better position than if you have done something wrong and the chance that you say something that sounds incriminating and/or the cop is not questioning in good faith.
In other words, the consequences of seeming suspicious with no evidence against you are much better for you than the consequences of saying the wrong thing.
