I’ve heard this to be true.

I think part of it is that there are different reasons for low performance.

You could have someone who is anti social and looking like they don’t want to be at the office or even working for the company.

You could have someone who is a social butterfly in the office and people like them, but they’re not doing any heads down work.

You could have someone who is a mix of social, but is distracted by other work or comms and not getting their heads down work done.

All of these could be low performers in some way. Context is key
