Biggest No-Nos for PhD students [10 to AVOID!]

Plagiarism is the fastest route to losing academic credibility—and it can even lead to PhD revocation. The warning is blunt: copying someone else’s ideas, wording, or work and presenting it as original violates plagiarism rules, even when the material could have been properly cited. The practical takeaway is equally direct: if the work is someone else’s concept or phrasing and it’s citeable, include a citation. That single habit is framed as the difference between legitimate scholarship and career-ending misconduct.

Beyond academic integrity, the biggest threats to a PhD career are behaviors that quietly derail progress. Inflating accomplishments to a supervisor—whether through exaggerating results, claiming work that wasn’t done, or “making stuff up”—is treated as a serious risk because even small distortions can resurface during write-up, data review, or future discussions. Honesty with data and with what’s actually working is positioned as the foundation for getting real help, not just praise. Another major trap is perfectionism: aiming for flawless work is portrayed as a guarantee of never finishing. Instead, the advice is to pursue “good enough,” complete tasks to a solid standard, and submit by deadlines—because perfection is described as the force that kills momentum.

Keeping momentum also depends on organization and learning habits. Relying on memory is labeled a common failure point; the solution is to maintain a lab notebook (or equivalent) and record ideas, experimental steps, details, and even thoughts in one place. The emphasis is on capturing information immediately—whether during lab work or quick conversations—so nothing important gets lost amid the daily churn of a PhD.

Mental resilience and productivity are tied together through small, deliberate practices. Celebrating “little wins” is recommended as a counterweight to the stress and anxiety that failures trigger. The argument is biological as well as psychological: setbacks feel real in the body, so acknowledging progress helps offset that strain and sustains enthusiasm.

Several social and strategic habits are also flagged. PhD students are urged not to neglect relationships outside academia—partners, friends, and hobbies—because those connections provide decompression and support during tough stretches. Relentless comparison is discouraged too; the only comparisons worth making are to one’s own past progress, since other people’s timelines and struggles vary widely and metrics can distort reality.

Finally, the guidance turns to risk management: avoid getting pulled into departmental politics and toxic behavior, ask for help as soon as a problem becomes unmanageable, and don’t drift through a PhD without a plan for life afterward. Since academic jobs are difficult to secure, having at least a rough idea of what comes next—industry, entrepreneurship, or another path—reduces the panic and regret that can follow graduation. The overall message is that a PhD succeeds when integrity, honest reporting, steady execution, good record-keeping, and proactive planning reinforce each other rather than letting avoidable mistakes accumulate.
