Taking into account career stalling
I think an interesting topic to discuss would be the facts and implications of career stalling - people finding that they cannot easily progress past a certain point in their career. For example, the "Peter principle" suggests that people are promoted to their "level of incompetence" and then fail to be effective or move up the career ladder. It would be interesting to know if there is much research showing whether this is true, and if it is how long it typically takes to happen, or what other reasons there can be for careers to stall. Also, it may have implications for career strategy e.g. if you can plateau after a short time in a sector, then it favours spending more time exploring different career options. This is because if you find a decent option, then spend more time exploring, then go back to the first option, then you can catch up to where you would have been in a few years, so the cost of exploration is less than if career stalling doesn't happen.
