Humans transfer knowledge most effectively when they are communicating in person. Of course this does not mean you will achieve the highest productivity in an office by putting 20 people in the same room, but it still says a lot about in office vs complete remote work.

A lot of companies create the type of culture where it's not pleasant to work in the office. However, having half you team work remotely on random days of the week isn't the right solution to this, and I don't think it could be justified by saying "I trust my employees". Just create the right team and the right environment. People will want to spend time together when there is inspiration and motivation involved.

There is a lot more to the implications of strong tacit information transfer that extends to how innovation ecosystems work. For anyone curious I would suggest finding the research around the subject.
