True introspection turns into a math puzzle when you want to go really deep. (It requires constant monitoring and logging of your own mind, and requires an insane amount of tests against self deception if you want to do it properly. Both of which are constrained by memory and compute power, which will likely not be sufficient if for no other reason than that you need to allocate some of it to other priorities.) I think it's a sign of wisdom to admit that it's too big of a challenge for an individual to rely on as a substitute for resources like this.
