The concept that resolved Epstein's confusion about two camps of expertise researchers finding opposite results. Kind learning environments have clear next steps and goals, repeating patterns, stable rules, fast accurate feedback, little human behaviour involved, and work next year that looks like work last year — chess and golf are the archetypes. Wicked environments have patterns that may actively fool you, rules that change if they exist at all, and feedback that is delayed, inaccurate, or absent. Narrow repetitive practice compounds into expertise in kind environments and can produce confident incompetence in wicked ones. Most modern work — management, entrepreneurship, programming — sits on the wicked end, where you want a much broader toolbox.
Origin
Daniel Kahneman heard Epstein critique the 10,000 hours science, asked for his email, invited him to lunch months later, and pointed him to Robin Hogarth's work on kind versus wicked domains.
Core principles
- 01Kind: clear goals, repeating patterns, stable rules, quick accurate feedback.
- 02Wicked: misleading patterns, shifting rules, delayed or inaccurate feedback.
- 03Deliberate practice works where a coach can watch you and correct everything you do wrong.
- 04Golf is a uniquely horrible model for most things humans want to learn.
How to run it
- 1
Locate your task on the spectrum
Judge how repetitive the patterns are, how stable the rules are, and how fast and accurate the feedback is.
Pro tip Ask whether work next year will look like work last year — if not, you're on the wicked end.
Watch out Most people assume their domain is kinder than it is because feedback feels informative.
- 2
Audit your feedback loop
Check whether you actually learn the consequences of your decisions, and whether the feedback could be reinforcing the wrong lesson.
Watch out Judges and many clinicians almost never learn the outcome of a decision, which is close to worst-case for judgement.

Match the training to the environment
In kind domains, use focused corrective repetition; in wicked ones, build breadth, varied problems, and generalisable models.
Pro tip Ericsson himself later caveated that the framework applies only where we know exactly how to be good and a coach can correct you.
Watch out Applying kind-domain practice to a wicked domain can make people more confident without making them better, and sometimes worse.
In the wild
A New York doctor became famous for predicting typhoid by palpating patients' tongues by hand; a colleague later observed he was spreading it himself with those hands.
→ His predictions kept coming true, so the feedback reinforced the exact wrong lesson — the textbook wicked environment.
A grandmaster's advantage rests largely on recurring patterns, which is also why chess is relatively easy to automate; managing and entrepreneurship have no such stable pattern base.
→ Epstein calls the caveat 'a pretty big loophole' in the deliberate practice framework.
Common mistakes
Importing golf-style practice into wicked work
Golf is the epitome of a kind environment where the situation isn't changing, which makes it a bad model for almost everything else people want to learn.
Trusting confident experience in a wicked domain
When feedback is delayed or misleading, repeated experience can build certainty rather than accuracy.
Is it for you?
Best for
Professionals deciding how much to specialise, and anyone designing training or hiring for a domain.
Not ideal for
Purely kind, closed-rule pursuits where the spectrum question is already settled.
From the transcript
“kind is like next steps and goals are clear rules repeat”
“wicked learning environments where patterns don't just repeat they might fool you rules may change if there are any feedback could be delayed or inaccurate”
“he was a more prolific spreader of typhoid than even Typhoid Mary”
