It shouldn't be rare in fields such as robotics, linguistics, psychology, cognitive science. It depends on the country/ies where cooperation happens - how these fields have evolved there in the research institutions and in the private sector, whether there are links between the two. I think that collaboration between science and humanities is much stronger in the English-speaking world, and particularly in the USA.

Otherwise, the sad reality is that people from the sciences think that those in the humanities do not know and do anything worth their attention, and vice versa - humanities scholars do not want (or are not permitted) to learn skills which are ''reserved'' for the sciences and math oriented. Again, it is a question of how research is organized in the respective countries and the moral of the people who teach and/or do research there. If they are not interested to advance or cooperate, they won't.

Brilliant! thank you Hristina

From my experience and research, this is particularly the case in developing online learning in higher education where those who speak the languages of pedagogy and digital technologies, respectively, rarely collaborate. Maybe it is just that: a language issue.
