Frame the career choice as a provisional hypothesis rather than an irreversible identity. Specify what you expect the work to provide—such as satisfaction, service, intensity, autonomy, or growth—and acknowledge which assumptions cannot be tested from outside the role. Enter the work for a bounded, meaningful period and observe routine conditions rather than reacting to one unusually good or bad day. At the end, compare lived evidence with the original predictions and update the decision. This approach supports committed action while preserving intellectual flexibility. It also prevents endless speculation before experience and sunk-cost loyalty after contrary evidence becomes available.

Origin

Nasser planned to use his first two working years as a doctor to test whether medicine delivered the meaning and satisfaction he anticipated. Extracted from Deep Dive with Ali Abdaal.

Core principles

  • 01Current beliefs should remain revisable
  • 02Actual work provides evidence that training cannot
  • 03A bounded experiment reduces speculative overthinking
  • 04Evaluation criteria should be defined before the test
  • 05One difficult day should not determine the verdict

How to run it

  1. 1

    State the hypothesis

    Describe why you currently believe the career will suit you and what it should provide.

    Pro tip Use observable expectations rather than identity statements.

  2. 2

    Name the unknowns

    Separate what training or observation has shown from what only doing the job can reveal.

    Watch out Confidence is not a substitute for lived evidence.

  3. 3

    Bound the experiment

    Choose a period long enough to experience normal work but short enough to permit deliberate review.

    Pro tip Set the review point in advance.

    Watch out Do not postpone evaluation indefinitely.

  4. 4

    Collect lived evidence

    Observe satisfaction, stress, impact, learning, relationships, and sustainability across many ordinary days.

    Pro tip Keep brief notes so extreme days do not dominate memory.

  5. 5

    Update the path

    At the review point, continue, modify, or leave according to the evidence gathered.

    Watch out Do not treat changing your mind as failure.

In the wild

Testing the first two years of medicine

A graduating medical student expects patient care and high-stakes responsibility to feel meaningful but knows student placements cannot prove it. They commit to working for two years, observe the job's actual effect on satisfaction and wellbeing, and then reconsider the path.

The eventual career decision rests on lived evidence rather than idealism or fear.

Common mistakes

Demanding certainty before acting

Some career information is unavailable until the person enters the role.

Judging from one bad day

A single outcome is too noisy to evaluate an entire professional path.

Is it for you?

Best for

It is best for people entering a profession whose lived reality differs substantially from training.

Not ideal for

It is not ideal when the experiment exposes someone to unacceptable safety, financial, or ethical risk.
