I agree with you that maintaining a consistent focus on the problem, instead of falling for substitution hazards, thinking well when it's very non-obvious how to think well, etc., is difficult. It is not the case that we are unaware of those issues and are not going to teach them.
The Seminar and the following two months of the year-long Fellowship are focused on loading/understanding the problem as much as possible. Succeeding in this is a good start, and those participants who have demonstrated the greatest proclivity at picking up the key points are also most hopeworthy for being able to pick up the skills you're talking about over the subsequent 11 months. For those who continue learning about the problem and will want to do original research (whether within the Fellowship or outside of it), focusing first on loading what's already out there is helpful for knowing what paths of thinking predictably fail and why they predictably fail in making progress on the problem.
Regarding the research skills you're talking about, we are going to invest a lot of effort into trying to have them transmitted (be it in a legible or illegible format), although even then, we don't expect most people to succeed at acquiring them.
Aside from that, we expect the [loading/understanding the problem as much as possible] part to improve the discourse, policy, and help people not waste motion, even if many of the people will acquire relatively partial models of the problem (relative to what is possible).
