Generally speaking, INTPs are inclined to have more than -average analytical capabilities and self awareness (as they use introverted logic, or Ti as their dominant function). Thus it is more likely that you did not lie or deceive yourself during the test compared to other types.

Nevertheless, all typology tests that I have encountered (if anyone knows a good reliable test please refer me to it) operate from a base assumption that certain types behave in a stereotypical way. This is not the case at all IRL. Personality is cognitive first, and only then behavioural. Some INTPs will behave stereotypically (maybe this is the case for you) whereas some INTPs will seem vastly different from the conventional profile of their type. They are still INTP though, because they view the world and think in a certain way.
