The paradox of doctoral training

Posted by , on 29 September 2025

Doctoral programs say they want the brightest, most creative, and motivated students. But once you enter, creativity often gets replaced by execution, independence by subordination, and discovery by survival. Why does this paradox exist, and what does it mean for the future of science?

The academic path looks simple on paper: PhD, to postdoc, to PI. In practice, most doctoral students never become principal investigators, and many who do spend more time chasing funding cycles than pursuing the questions that first drew them to science. Yet, in this high-pressure system, the bottleneck begins far earlier – during the PhD itself.

Doctoral training should be about developing the ability to ask new questions, test risky ideas, and learn through failure. Instead, many students are trained mainly as “hands”. They join ongoing projects, collect and analyze data, write papers, and keep the lab productive. That technical training is valuable, but it does not cultivate the creative independence required of a scientist.

This is a structural trap. A PhD student may be talented, motivated, and full of ideas, but the funding architecture rarely treats them as independent scientists. Instead, they are seen as extensions of their PI: useful hands within someone else’s grant, not originators of their own research. Their ability to explore depends entirely on whether a PI has the time, money, and open-mindedness to support side projects. Exploration in science rarely follows a straight line: when you begin working within a PI’s broader framework, small and unexpected findings often emerge. These fragments, seemingly minor at first, can combine later to sharpen or even overturn an initial hypothesis. But following up on them usually demands extra experiments, financial investment, and time – luxuries a student cannot access independently. Awarding small research grants directly to students could support such exploratory work, giving them the chance to refine an idea, craft a proposal, and navigate submission guidelines. This process itself is vital training in independence – not only in how to build a project, but also in how to cope with the inevitability of rejection and try again.

Funding systems reinforce the trap. In the US, there are prestigious opportunities such as the NIH F31 predoctoral fellowship or the NSF Graduate Research Fellowship Program; funding programs that allow students to pursue independently led scientific projects. These awards are fiercely competitive, but applying is itself a form of training: students must learn the system, engage with program officers, and craft proposals that stand a chance of success. Even without funding, the experience prepares them for future large-scale NIH or NSF applications. By contrast, in Europe such funding opportunities for student-led projects are scarce. Large initiatives like Marie Skłodowska-Curie Actions fund doctoral networks, but the money is formally awarded to the PI, not the student. Seed grants for doctoral candidates are rare, and existing options, such as EMBO or Company of Biologists travel grants, support mobility and training, but not the independent pursuit of a research project.

The result is a predictable cycle: new cohorts of doctoral students become experts in executing tools, presenting data, and meeting deadlines, but not necessarily in generating ideas that push science forward.

Lab culture compounds this problem. When the lab leader values only hierarchy, the PI’s ideas reign supreme. When junior researchers don’t feel safe or encouraged to voice critique, propose hypotheses, or share their own ideas – creativity is stifled. But in labs where every opinion is listened to, where mistakes are not punished but discussed, where funding applications from students are encouraged regardless of seniority – that is where scientific innovation grows.

This is not a problem of talent. PhD students are often able to push the frontiers of science, but only if given the resources and freedom to pursue new ideas. If doctoral training is to form scientists rather than technicians, then structures should be in place to make this possible: funding lines that support student-led discovery, PIs who act as co-mentors rather than gatekeepers, and programs that reward exploration as much as publication.

The paradox is clear. Doctoral programs attract creative minds, but the system too often suppresses the very qualities it claims to seek. And the consequence is equally clear: creative people leave academia for start-ups, biotech, and other environments where risky ideas are supported and failure is treated as progress. If this trend continues, academia risks not only losing its brightest people but also its role as the primary driver of scientific discovery.

  1. This seems to be a gross generalization based on the experience of one person. While I don’t doubt that there are situations in which there are issues with PIs limiting creativity and scientific freedom for PhD students, it is important to consider that this is not the case for the vast majority of PhD candidates. That said, it also appears that you fail to fully understand the system in place for hiring and funding PhD students, complaining that the PI controls the money when they are the ones who have indeed earned it by applying for grants etc. while the PhD student they select is often chosen after funding has been awarded. A PhD is just as much about learning and acquiring skills in research (techniques, teambuilding, labwork etc.) as it is about creativity and pursuing scientific questions you yourself pose. Communication between the PI and PhD student is essential for everything to work well, and expectations for things to be one way or another should not impact how the reality is perceived. Sometimes we should be grateful about the opportunities we have and proud that we have earned such prestigious and sought-after positions. That isn’t to say issues should be overlooked, but I think communicating with a PI about these kinds of things is far better than choosing to rant about it online which may or may not look bad for you in the end.

  2. We consider the Node to be a supportive community, and we welcome authors to write about their diverse views and experiences. We believe that authors should be able to do so without fear of repercussion.
