The worst a leader can happen is getting caught being gullible. Gullible does off course have a very negative connotation, as it means dumb trusting. The point however is, that to understand what is really asked, one has to know more about this world than possible. So one has to be gullible to be able to live in this world.
So it is impossible for a leader to prevent being used for his gullibility. Not only because it would make life a living hell. But also because it would that you could trust nobody. Which would end in the impossibility to work with anyone.
Off course trust and gullibility does not mean that you can not be interested in someone else. And maybe that is where the solution lies to prevent misuse of gullibility. Although interest is a form of gullibility. As you need to trust the other to answer your questions truthfully. Byt by asking questions, you lessen the possibility that the other will take advantage of your trust. Because unanswered questions point to a problem that needs to be research, so you can help finding a solution.
