Drawn from decision science's explore-exploit dilemma, this heuristic replaces an unusable exact formula with two practical rules. First, apply an uncertainty bonus: when options are otherwise equal, weight the one you know less about, because unknowns are where learning lives. Second, use the upper confidence bound rule, translated as optimism in the face of uncertainty: choose the option with the best realistic best-case outcome. Individual decisions may still go badly, but over a lifetime this strategy provably minimizes regret — the gap between what you got and what you could have gotten with perfect foresight. The final move is knowing when to stop exploring and exploit: sit with what you found and actually enjoy it, rather than chasing novelty forever.
Origin
Alex Hutchinson, a physics-trained science journalist, went down the mathematics of the explore-exploit dilemma while writing his book on exploration, found the exact formulas intractable in the real world, and distilled two usable heuristics from the underlying math.
Core principles
- 01Every choice is a bet between exploiting what you know and exploring what you don't
- 02The value of an option includes what it teaches you, not just its expected payoff
- 03You can't eliminate regret, only slow how fast it accumulates
- 04Optimism about realistic upside beats pessimism when outcomes are unknown
- 05Neither pure exploration nor pure exploitation is correct — the mix is the skill
How to run it
- 1
Frame it as explore vs exploit
Recognize that the decision is a trade-off between exploiting a known good option and exploring an uncertain one. Neither is automatically right.
Pro tip The fact that it feels like a dilemma is the signal you're at a genuine explore-exploit fork, not a trivial choice.

Apply the uncertainty bonus
Give unfamiliar options a weighting bonus proportional to how little you know about them. All else equal, lean toward the choice that will teach you something new.
Pro tip This is exactly the bias behind picking the four-star restaurant with 10 reviews over the one with 100 — the unknown carries hidden learning value.
Watch out The bonus is one factor among several, not an override; don't chase novelty for its own sake.

Be optimistic in the face of uncertainty
For each realistic option, picture the best plausible outcome and favor the option with the strongest realistic upside. This is the plain-language version of the upper confidence bound algorithm.
Pro tip A lower-paid job with a path to your dream role often beats a stable higher-paid one precisely because its realistic upside is what would make you happiest.
Watch out Realistic is the key word — don't buy the lottery ticket just because its best case is being a millionaire.

Test with regret minimization
Ask which choice you're least likely to regret over the long run. You rarely regret the shot you took; you regret the one you never risked.
Pro tip You're more likely to wish you'd asked that person to dance than to regret asking and being turned down.

Know when to exploit
Once you've discovered something good, deliberately stop and enjoy it. Endless exploring without ever settling is as broken as never exploring at all.
Pro tip Give yourself permission to play the song you love on repeat — exploiting a good find is part of the strategy, not a failure of it.
Watch out Treating every fork as a reason to explore leads to delayed gratification with no payoff — winning the marshmallow test forever but never eating the marshmallow.
In the wild
One offer pays more and is stable; the other pays less and is shakier but has a clear pathway toward the work you actually dream of doing. Applying optimism in the face of uncertainty, you weigh the realistic best-case of each. The stable job's ceiling is more of the same; the riskier job's realistic upside is the career you most want. All else roughly equal, the heuristic favors the shot on the pathway job, because that's the outcome that would make you happiest if it lands.
→ You take the option whose realistic upside best matches what you truly want, minimizing long-term regret even if any single outcome is uncertain.
Harvard scientists analyzed 1.6 million food-delivery orders and found that when price and ratings are equal, people lean toward the option they know less about — a dish they've never tried, or the four-star restaurant with only 10 reviews over an identical one with 100. This is the uncertainty bonus operating intuitively: unfamiliar options are attractive precisely because they carry the most potential to teach you something new about what you like.
→ Diners naturally weight novelty, illustrating the uncertainty bonus already at work in everyday micro-decisions.
Common mistakes
Treating explore as always the right answer
The explore-exploit dilemma is a genuine dilemma, not a rule to always take the road less traveled. Sometimes the correct move is to exploit and enjoy what you've already found.
Confusing optimism with recklessness
Optimism in the face of uncertainty means favoring the best realistic upside, not the best fantasy outcome. Ignoring the realistic filter turns the heuristic into buying lottery tickets.
Never cashing out the gratification
Perpetually deferring to exploration means you accumulate discoveries but never sit and enjoy any of them, which drains the satisfaction the whole strategy was meant to produce.
Is it for you?
Best for
Anyone facing repeated open-ended choices (career, relationships, hobbies, daily routines) who wants a principled way to decide when to try something new.
Not ideal for
High-stakes one-shot decisions where a bad outcome is catastrophic and cannot be recovered from.
From the transcript
“the less you know about an option, the you give a bonus that's proportional to how little you know about it”
“optimism in the face of uncertainty, that you should be optimistic about the choices you make”
“if you're optimistic in the face of uncertainty, this will minimize your regret”
