>But I also think it's pretty hard to foster an environment where people of every seniority level feel comfortable doing that.

That's because pretending to be unsinkable is much easier than working to prevent the ship from sinking. Especially when there's a perception that the problem carries very low risk. That creates situations where there's little individual benefit and a lot of reputational risk for raising the alarm.

To fix this you have to intentionally create a culture that aligns individual and organizational incentives around the behavior you want to see encouraged.
