1 - Choose mentors as if your career depends on it because it does
Research published in Nature Communications showed that co-authoring with an established scientist can generate a career advantage lasting for several decades. But mentorship can also become a serious career trap. A more recent analysis of 245,000 collaborations across 22 scientific fields found that supervisors with weak, irrelevant research records can actively damage the prospects of young researchers. https://pachecotorgal.com/2024/08/16/o-melhor-conselho-que-se-pode-dar-a-um-jovem-investigador-fuja-como-o-diabo-da-cruz-dos-catedraticos-de-obra-irrelevante/
2 - Do not remain in your supervisor’s shadow
A postdoctoral position must not become an extended PhD. The decisive transition is from advancing someone else’s agenda to defining original questions, leading papers, securing funding and building collaborations under your own name. Mentors may open doors, but only the intellectually cowardly remain permanently in their shadow and eventually discover that those doors were never truly theirs. https://19-pacheco-torgal-19.blogspot.com/2025/07/dois-requisitos-essenciais-para-que-os.html
3 - Prioritise impact, not academic paperwork
A Nature analysis of approximately 45,500 researchers found that 41% of postdoctoral researchers eventually left academia. Those who produced at least one paper among the top 5% most cited in their field and year were significantly more likely to secure a faculty position. https://pachecotorgal.com/2025/01/28/estudo-revela-a-receita-para-um-jovem-pos-doutorado-conseguir-emprego-nas-universidades-dos-paises-do-primeiro-mundo/
4 - Develop intellectual audacity
Nobel laureate Alain Aspect argues that frontier research requires a degree of “arrogance.” Not vanity, but the confidence to challenge established authorities, reject convenient assumptions and pursue ideas that respectable opinion considers unrealistic. Scientific breakthroughs rarely come from obedient researchers carefully protecting the consensus. They come from those prepared to risk being wrong before everyone else realises they were right. https://pachecotorgal.com/2024/07/15/vencedor-de-premio-nobel-aconselha-arrogancia-aos-jovens-investigadores/
5 - Science has no place for cowards
Science is not merely a profession. It is humanity’s organised rebellion against ignorance, disease, suffering and fear. That rebellion is now harder. Evidence is manipulated, expertise is ridiculed and machines can generate fluent falsehoods faster than anyone can refute them. Artificial intelligence will process evidence, detect patterns and draft your papers. But it cannot possess courage, assume moral responsibility or risk a career in defence of an inconvenient truth. That is precisely why independent judgement and intellectual nerve are becoming the most valuable qualities a researcher can possess. Yet too many researchers retreat into silence to protect their careers. That silence is not neutrality. It is surrender. Scientific courage means defending facts when lies are louder, challenging authority when obedience is rewarded and pursuing inconvenient truths when ignorance remains profitable. Those unwilling to confront falsehood, power and fear should seek a safer profession. https://pachecotorgal.com/2025/04/09/now-is-not-the-time-for-despair-how-to-defend-knowledge-integrity-and-democracy/
PS - The "image" above contains a particularly memorable quote about courage, one I have mentioned before. At the end of the post below, I return to that idea and reflect on why courage matters more than ever. https://19-pacheco-torgal-19.blogspot.com/2023/11/audacious-academics-fearlessly-putting.html
