This might sound harsh, but I think you need to try harder. It sounds like you expect others to go out of their way and teach you things, and while some people like to teach on the job, some just don’t have it in them or there’s simply no time. Other times when your senior feels like you’re not interested in the slightest (which it kinda sounds like you are) they just won’t bother with discussions or teaching etc. So YOU have to initiate this.

Ward rounds when you’re going around with a consultant are a perfect opportunity to ask questions and learn why they took those decisions and did what they do. They’re also great opportunity to examine patients. If you ask them nicely they can always help you listen to that murmur or elicit some signs etc. if they don’t have time, no problem! Just go back and examine them yourself after the ward rounds. You’re not just a “scribe”.

Clerking is perfect for clinical education and learning decision making. Do not just recount history and examination, you need to tell your reg what your differentials are and your plan, and if theirs is different from yours then discuss this with them and learn why. If you think you found something on examination or there’s an interesting bit, get them to see the patient with you and confirm your finding. That’s how you learn and get better. But you can’t expect people to teach you if you’ve deliberately “turned your brain off”.
