More than 40% of postdocs leave academia, study reveals

Scale of Attrition and Pipeline Math

• Many expected a much higher exit rate than “>40%,” given limited professor jobs and shrinking tenure lines.
• Others note academia is a pyramid by design: one professor can train many PhDs and postdocs, so most must leave at some stage.
• Back-of-envelope US numbers in the thread suggest the majority of PhDs will never get tenure; some argue even that estimate is optimistic.

Is 40% Leaving Good, Bad, or Inevitable?

• One camp: attrition is natural and even healthy; not everyone should stay, and industry benefits from well-trained researchers.
• Another: 60% staying suggests inbreeding, misaligned incentives, and a system that traps people with “once I’m there…” thinking and sunk costs.
• Several argue the important question is how many don’t even attempt a postdoc after seeing the odds.

Postdocs as Labor and Training

• Recurrent view: postdocs are underpaid, unstable, and often exploited as cheap, disposable research labor.
• Others stress variation: some postdocs (especially in certain CS and engineering contexts) are reasonably paid, autonomous, and genuinely developmental.
• Debate over whether postdocs are primarily “training” versus fully expert roles; some see “training” as rhetoric to justify low pay.

Working Conditions and Culture

• Many report overwork, bullying PIs, authorship fights, visa leverage, and pressure to publish quickly in narrow, trendy areas.
• Others say their labs were collegial, mentoring was good, and weekends were for passion, not coercion—experiences vary heavily by country, field, and advisor.
• Instability of serial 2–3 year contracts is a major deterrent to family life and long‑term planning.

Incentives, Innovation, and Mission

• Strong criticism that metrics (paper counts, citations, grant dollars) dominate over correctness, originality, or societal usefulness.
• Some defend the current system as a pragmatic way to allocate scarce funds and focus on long‑horizon knowledge, leaving near-term applications to industry.
• Concern that grant structures discourage risky or student-originated ideas and that many good ideas die when early‑career researchers exit.

Alternatives and Advice

• Many ex‑academics describe higher pay, more stability, and equal or greater impact in industry or startups.
• Common advice: choose supervisors and labs carefully; don’t do a postdoc unless it clearly serves your goals; accept that leaving academia is often the rational choice.
