After I take my car in for maintenance, new tires, oil change, repair, etc. I will notice something different about how the car drives: brakes differently, steering is slightly off, etc. My first thought is that the mechanic may have done something to the car to result in me coming back for further service.
I know that this does happen in certain repair shops, but it happening every time I take my car in to different shops over my lifetime with different cars, is ludicrous, and I know that it is some sort of emotional response that I am having. Yes, a few times I have needed to get a follow-up repair, but I believe, after processing, on those few occasions it was coincidence.
I think my immediate suspicions are some sort of cognitive bias, but uncertain which one.
