Many times we feel that "the reasoning doesn't make sense," but the problem is often not about how well you express yourself or whether the other person is smart, but rather that your words simply haven't entered the other person's system that truly functions. In other words, your logic hasn't found the "effective entry point." First, the rules are different: you're using facts and logic, while the other person might be considering stance, identity, or emotions; both of you are not operating within the same judgment standards. Second, the position is wrong: in some scenarios, there is a power imbalance; you are speaking reason, but the other person holds the decision-making authority, so reason is easily perceived as a "challenge" and suppressed. Third, conflicts of interest: if your conclusion is valid and would cause the other person to incur costs or change the distribution, they might refuse to admit it, even if they understand your logic. Fourth, for stability: some issues everyone actually knows deep down, but clarifying them could damage relationships or order, so the system instinctively chooses to "not say it outright." Fifth, lack of feedback: if saying the right thing doesn't lead to results, and saying the wrong thing doesn't have consequences, then the logic has a hard time truly entering reality; it remains only in discussion. So, many times it's not that you aren't clear enough, but that your logic hasn't connected to the other person's system that can execute and feedback.
