************************* MRBANKS EXPERIMENT DATASET **************************

The data stored here come from a lab-in-the-field experiment, called Mr. Banks,
where volunteers are given a controlled set of financial information -based
on real data from worldwide financial indices- and they are required to guess
whether the market price would go up or down in each situation. Data is used
to explore basic statistical traits, behavioural biases and emerging
strategies. More details can be found in the following publication:

    Imitation and Win-Stay Lose-Shift strategies emerge as unintended patterns
    in market direction guesses. PLoS ONE. (2016)

EXPERIMENTAL SETTING

The experiment was carried out inside the context of DAU Festival, a board game
fair held in Barcelona during the weekend of 14th and 15th of December 2013.
The event was organized by the Institute of Culture of the City Council and
attracted 6,000 attendants from Barcelona and its surroundings. The experiment
is framed inside the Pop-Up Experiment concept. Participants did not know in
advance the details of the experiment and were asked to play with Mr. Banks
(for the participants the experiment was referred as a game) via an interface
specifically created and accessible through identical iPads only available in a
controlled area -a space with chairs isolated from the rest of the festival-.
At least three researchers simultaneously supervised the experiment at all
times, preventing any interaction among the volunteers and avoiding that
anybody was repeating the experiment. In order to satisfy privacy issues, all
personal data about the participants were anonymized and de-identified in
agreement with the Spanish Law for Personal Data Protection and the
institutional review board and data protection commissioner of the Universitat
de Barcelona. An online informed consent was given by participants for their
clinical records to be used in this study.


DATASET CONTENT

The MrBanks dataset file contains all recordings needed for reproducing the
experimental part of the paper. 283 volunteers were recruited to participate
in the experiment in the DAU Festival of Barcelona. The participants took
18,436 valid decisions (89 times they ran out of time) and made 44,703 clicks
on the screen.
