That's up to you, but context matters and that simply isn't the title. That finding too is not well supported by the article, sample size = 1 and the company they looked at is not exactly a typical company either. Imnsho this paper is very low quality.

It is entirely possible that these conclusions (which by themselves are not all that shocking or novel) hold true over larger samples and across multiple types of company but that's not what they did. They looked at one entity:

"We study the impact of sitting together in the office for software engineers at a Fortune 500 online retailer. This firm gave us access to the online feedback that engineers write about each other’s computer code as well as metrics of engineers’ programming output. "

So they base the entirety of this conclusion on code review comments and lines-of-code produced or something like that. That makes the conclusion even less supported than if they had done some actual research.

For a statement like this to hold you would at least need a control and a larger sample.

Which seems very consistent with everything I've seen over a fairly long career. I'd add not just co-workers but also other interactions with industry peers.
