Agreed, while I prefer deep work in solitude, there is a lot of literature which suggests that collaboration enhances outcomes. Random example: https://www.sciencedirect.com/science/article/abs/pii/S00221...

Not sure that literature really contradicts the original hypothesis. The abstract (can't download the full text without buying it) seems to be implying that they found there is motivation for working in groups and made work more fun (or rather, even just providing cues that make people feel like they are working in groups) but didn't really touch on innovation or collaboration as it relates to brainstorming/ideation.

I think it's important as the poster above you said, not just take the word research at face value. I'm sure that there may be studies that show collaboration can lead to good ideation and outcomes also, I just don't think this one is that.

Some notes from the abstract:

> ... examined cues that evoke a psychological state of working together ... which increased intrinsic motivation as people worked alone.

> Outcomes were diverse, e.g., task persistence, enjoyment and, 1–2 weeks later, choice.

> These cues also increased feelings of working together but not other processes.

> The results suggest that cues of working together can inspire intrinsic motivation, turning work into play. The discussion addresses the social–relational bases of motivation and implications for the self and application.

In my opinion, collaboration certainly enhances outcomes, but only when it alternates with solitary work.
