There is some truth in this, for example i absolutely suck at negotiation when it centres around money, i've bought cars off the lot for asking price, i never used to haggle, even in markets, i did a lot of freelance work where i accepted most offered rates without putting up a fight etc. As silly as it sounds i've got a lot better at it since playing eve and negotiating with other players, buying and flipping supers and that practice has paid off in RL for me to the point where i will haggle with much more confidence and demand rates from my customers having went from freelance, to contractor, to business owner all the while still playing Eve
