I agree with nissy actually. Driving a car does not require one to go into the levels of intuition - which is where overthinking can break things down. Thinking "ooh nasty noise maybe I had better check the wheel bearings, and steer carefully for now" is not the same as a reading stopping dead while you think of all you have learned about the Moon card. That stops the flow. Thinking about wheel bearings does not stop you driving.
Undisputed, I guess, altough the comparison isn't exactly fair. Thinking instead too hard about what foot to use for what pedal in what order might have an influence on your driving style indeed.
Anyway, the question I thought this little sided-discussion was about was: If you have thought a lot about how tarot works and if you have an opinion about it, can that have a negative influence on your reading abilities some other day while you are not actually thinking about it at this very moment?
I wouldn’t bet that it has no influence at all, but I'd guess that after all it hardly matters. And I wouldn’t accept it as an excuse not to gain more knowledge about tarot in general.
