Ask HN: Psychologists in modern companies. Do many have them and if not, why?

That's been puzzling me for some time. From the experience of being in tech industry for about 10 years, I have an impression that significant part of all "problems" teams experiencing are communication issues. Yet when I propose something like say, "You noticed that 60% of our problems are communication. Let's have a person for 'debugging' those, i.e. HR/Psychologist", people just ignore the idea as if it wasn't there. That's so wasteful in my opinion. Are other readers of HN experiencing similar situation? Do you have a person to whom you can talk about communication issues at your workplace? If yes, has it proven to be effective? Thank you.
