In all fairness, it's really due to universities not focusing at all on teaching research. Having studied (and taught) at a research university in the Netherlands, I can tell why my friends... well, didn't give a shit about their theses. For them, it simply is a longer essay with a predefined structure and some guidelines on the exact word count and referencing style.

It's sad, but it's not really about Turkey. It's global, and caused by the universities not caring themselves, and not teaching students how to write.
