Does this sound like the set of challenges you might be facing?

• I’ve been reading and watching everything I can on a new field and I feel like I’m getting good at it
• I’m genuinely good at this now and I’ve gone fully on autopilot
• I only ever read and learn inside my own specialty, and my ideas have started to feel inbred and predictable
• I can nail this skill perfectly in the one familiar setup I practiced in, but the moment anything about the situation changes I’m lost
• I tried to walk someone newer through how I’d handle this and kept hitting questions I couldn’t answer cleanly

7. The Expertise Reversal Effect: When Help Becomes Harmful
   The expertise reversal effect, identified by Fred Paas, John Sweller, and colleagues, is the finding that instructional supports helpful for novices — worked examples, detailed guidance, redundant explanations — become ineffective or actively harmful as expertise grows. The mechanism is cognitive load: supports that reduce extraneous load for novices add extraneous load for experts who have already automated the relevant processes.
8. Collect models deliberately from fields outside your specialty
   Choose one model per quarter from a discipline you do not work in and learn it well enough to explain it.

9. Use constraint-based drills to isolate one component
   Remove degrees of freedom so attention concentrates on a single weak sub-skill.
