Epistemic status: quick insight that seems true in many cases
Your ability to notice that something is wrong trades off against your ability to convince others that said thing is, in fact, wrong. Suppose you discover a way in which the mainstream narrative is wrong in whatever field - maybe a famous math paper has an embarrassing typo, making the conclusion false. It would be very easy to convince others of this, if you knew. However, it's very difficult to discover such mistakes, because they're very rare. The flip side also seems true - if it's fairly easy to discover that the mainstream narrative on something is wrong, then it's likely to be extremely difficult to convince others of this. Politics is a great example of this; convincing others that your views are correct is nearly intractable, and often far more difficult than figuring out the correct view on specific issues.
To the extent something is easy to convince everyone of, once discovered, it's likely to have already been discovered and therefore become mainstream. Society is hard to exploit in that sense - if it's easy to discover and easy to spread, it would have already happened.
If you want to change society, you can move along the Exploitability/Explainability Frontier, either spending your time and energy looking for exploits that are relatively easy to explain, or spend it trying to explain exploits that were relatively easy to find. These are two distinct sets of research problems, and it seems worth distinguishing between the two.
