Seems like a lot of survivorship bias here.
I think intensity is a symptom of circumstance not a cause for them.
If you're a startup that's on the verge of transitioning from broke to huge success, I'd imagine everyone would be bringing a lot of intensity to push it over that line.
If you're an established company with a track record of responding to record profits with layoffs, then I don't think it's fair for you to expect your employees to share your enthusiasm.
Absolutely survivorship bias, as well as - intensity on the right things / right direction / level of decision making are important.
Go yell at your C-suite / directors with equity that have/will have F-you money from the success of the business. Don't think your ICs 3 levels down the hierarchy making 1-3x inflation-level raises will be as driven.
"survivorship bias" is becoming the biggest excuse for smart people who is afraid of taking actions
"Necessary but not sufficient" conditions are still necessary.
