The issue isn’t the degree itself, but the mindset it encourages. Academic training prizes caution, precision, and exhaustive analysis.

A 2014 US study found that over half of PhD students were primarily influenced by mentors—not by labor market trends or long-term prospects. At elite institutions like ETH Zurich, generous funding, competitive stipends, and institutional prestige can make the transition from a master’s to a PhD feel almost automatic. Few pause to ask whether it is a strategically sound move.We often justify the choice with references to “deep expertise” or aspirations for intellectual autonomy, which are all worthy motivations.
