There is enough social psychology research to suggest that most of the time people are more efficient alone than in a group, although some tasks take more than one person. Process gain vs process loss, social loafing, groupthink, etc., if you put four people on a team you might get 200%, not 400% return, or worse.
Interesting, for complex tasks that require thought, the most efficient grouping tends to involve groups with diverse backgrounds and a work culture that values disagreement… which is basically the opposite of what’s going on in American government right now, lol.
“By the time I explain how it needs to be done, I could have just done it”
This is why I so frequently get overwhelmed at work. I would always rather do things that talk about doing things, so I just do the things, and end up owning everything
