Why do some academics so often publish (letters) outside their field?

The letter to the editor discusses the phenomenon of academics in the Czech Republic publishing articles outside their field due to pressures related to evaluation, funding, and rewards in the scientific community. This practice is driven by the emphasis on quantity over quality, with some researchers submitting work to journals completely unrelated to their expertise or even to predatory journals. The letter highlights how this behavior is incentivized by financial bonuses and rewards, leading to a potential lack of meaningful contributions in the authors' actual field of study.
