Two frames, one decision.

Our adaptation

A between-subjects adaptation of Tversky and Kahneman's (1981) Asian disease problem: each participant is randomly shown either the gain frame (people saved) or the loss frame (people who die) with equal probability; the sure option comes first and no country name is used. Round 2 tests attribute framing (Levin et al., 1998): the same ground beef is labeled '75% lean' or '25% fat' (at random) and rated from 1 to 7. Round 3 tests mental accounting (Tversky and Kahneman, 1981): having lost either the ticket or the same amount in cash (at random) at the theater door, would the participant buy a ticket? A final question presents the same outbreak in the other frame.

Differences from the original study

  • The scenarios are hypothetical; there is no reward.
  • No country name or the word 'Asian' is used (Many Labs also removed it).
  • The theater scenario uses Turkish lira amounts.

Measured variables

The columns of the open data file. List fields are expanded into numbered columns (for example rt_60, est_3); JSON columns contain only numbers and fixed stimulus names.

ColumnTypeDescription
framegain | lossRound 1: frame shown (gain | loss; randomly assigned).
picksure | riskyRound 1: program chosen (sure | risky; main measure).
pick2sure | riskyFinal question: program chosen when the same outbreak is described in the other frame (for within-person consistency; should not be used in the between-subjects analysis).
attr_frameintegerRound 2 label frame (0 = '75% lean', 1 = '25% fat'; random).
attrnumberRound 2: rating of the ground beef from 1 to 7.
theatercash | ticketRound 3 scenario (cash = lost cash, ticket = lost ticket; random).
buy0 | 1Round 3: would still buy a ticket (1 = yes, 0 = no).
Columns present in every file (14)
row_idstringRow code. Regenerated at random in every release; it does not identify a person and cannot be matched across releases or experiments.
experimentstringShort name of the experiment (URL slug).
experiment_versionintegerVersion of the answer format. For experiments whose format changed, only the current format is published.
dateYYYY-MM-DD | YYYY-Www | YYYY-MMDay the answer was given (Istanbul time). If fewer than 5 answers share the same day, language and device, it is coarsened to the ISO week, and to the month if that is still too few.
date_precisionday | week | monthPrecision of the date column.
langtr | en | (boş)Interface language. Language recording started in the first week of October 2026; for earlier answers it is known only in experiments whose stimuli depend on the language, and empty otherwise.
devicedesktop | mobile | tablet | (boş)Device class reported by the browser (class only; browser details are neither stored here nor published).
sourcesite | embedWhere the answer came from: the balabs site or the experiment embedded on another site. The embedding site is not published.
modefree | daily | challenge | race | session | (boş)Play mode in scored experiments: free play, daily round, challenge, race room, experiment session. Empty for unscored experiments and for older answers that did not store it.
color_visionnormal | rg | by | contrast | (boş)In color-based experiments, the color vision mode the participant chose: normal, red-green, blue-yellow or high contrast. Stimuli are generated along different axes per mode, so compare within a mode. Empty for other experiments.
first_play1Every row is a participant’s first play of this experiment (always 1). Replays are stored only as leaderboard scores and are not part of the open data.
seen_beforeyes | no | unsure | (boş)Participant’s own report of whether they had seen this experiment or its known answer before (in experiments that ask).
duration_snumberTime from the start of the experiment to submitting the answer, in seconds (measured in the browser, 0.1 s).
play_scorenumberLeaderboard score of the first play (scored experiments; defined on the method card). Empty for unscored experiments.

Exclusion criteria

The server requires the round-1 frame and choice; invalid answers are rejected. Values from the extra rounds are collected in the browser. Only frame and pick should be used for the between-subjects comparison.

  • Only each participant's first answer to this experiment; replays are not included.
  • Simulated rows, bots, banned and sample accounts are not included.
  • Answers before 3 October 2026 are not included (the first day the open data notice was live).

Scoring

This experiment has no leaderboard score. The crowd result is the share choosing the sure option in each frame.

Version notes

  • October 2026

    The interface language (lang) started being stored with each answer; for earlier answers it is known only in experiments whose stimuli depend on the language, and empty otherwise.
