Across seven decision-from-experience experiments, participants repeatedly sample outcomes from two (or more) lotteries of varying payouts and skewness and then choose between them. Studies 1–4 (exp0–exp3, N=99, 250, 250, 500) use a sampling-then-choice "broker game" in which participants sample 30 outcomes per option per game before making a single choice, with normal/catch/disskewed/conskewed conditions. Studies 5–7 (exp4–exp6, N=71, 85, 45) use repeating multi-armed bandit games (30 or 60 trials) where participants learn option values across trials. The paper tests whether apparent skewness preferences reflect intrinsic skewness seeking or simply a preference for frequent winners (aiming more wins than losses), and shows a reinforcement-learning model capturing frequent winning plus intrinsic skewness provides the best account of choices.

Transcript
You play the role of a stock broker. On each decision you see two stocks side by side: the LEFT stock and the RIGHT stock. For each decision a history of the past 30 daily dividends of both stocks is shown, pair by pair (each pair shows one dividend from the left stock and, next to it, the same day's dividend from the right stock). After you have watched all 30 pairs, you decide which stock you want to draw a dividend from. Press B for the LEFT stock and A for the RIGHT stock. At the end one of your decisions is selected randomly and pays you that dividend as a bonus. Decision 0: the 30 dividend pairs (left, right) were: (436, 418), (436, 418), (436, 472), (382, 418), (436, 418), (436, 418), (436, 418), (436, 472), (382, 418), (436, 418), (436, 418), (436, 418), (436, 418), (436, 418), (436, 472), (436, 418), (436, 418), (382, 418), (436, 418), (436, 418), (436, 418), (436, 418), (436, 418), (382, 472), (436, 418), (436, 418), (436, 418), (382, 418), (436, 472), (436, 418).

You play the role of a stock broker. On each decision you see two stocks side by side: the LEFT stock and the RIGHT stock. For each decision a history of the past 30 daily dividends of both stocks is shown, pair by pair (each pair shows one dividend from the left stock and, next to it, the same day's dividend from the right stock). After you have watched all 30 pairs, you decide which stock you want to draw a dividend from. Press A for the LEFT stock and B for the RIGHT stock. At the end one of your decisions is selected randomly and pays you that dividend as a bonus.

You play the role of a stock broker. On each decision you see two stocks side by side: the LEFT stock and the RIGHT stock. For each decision a history of the past 30 daily dividends of both stocks is shown, pair by pair (each pair shows one dividend from the left stock and, next to it, the same day's dividend from the right stock). After you have watched all 30 pairs, you decide which stock you want to draw a dividend from. Press A for the LEFT stock and B for the RIGHT stock. At the end one of your decisions is selected randomly and pays you that dividend as a bonus.

In this task you earn points by repeatedly choosing among slot machines. The task is played as a series of games; each game has its own machines, and the same machines stay available for the whole game. On each turn you pick one machine; right after your pick, one draw is revealed for every available machine showing what it would have paid, and you receive the draw of the machine you chose.
