I don't know.... if only we have something like hard data from things like investing that could prove that women are better and making long-term decision and are less likely to make a rush decisions based on short-lived noise. You write like it's something we know from at least from early 2000s. It's not like it's a strong and growing consensus now, right?
I think the better statement would be both are emotional, which is simply part of being human.
The difference is women are taught very early to regulate and cope.
Ofc none of this is 100%, nothing involving people is 100%, but emotional regulation, coping, and patience within your emotions is something women have more practice with.
I’m not saying no woman ever has bankrupted the family savings to buy a positive emotion inciting vehicle, but the numbers there would be…less.
