*** This is the readme file for data files for "The Wisdom of Crowds in Matters of Taste." *** 
There are 3 data files in total, 1 for Study 1 and 2 for Study 2.
There are also 2 .r-files with the code for all of the analyses.

The sample sizes in both studies were obtained by running for a certain time period (e.g., until the end of the quarter) and terminating data collection if at the end of that time period, the sample size exceeded an intuitive threshold.  We did not conduct any analyses on the data for either study until after data collection had been terminated.  We did not collect measures other than those reported.
