data("Firstnames") Participants were presented with 15 pairs of boys names in random order. On
each trial, their task was to choose the name they would rather give to
their own child. The pairs of boys names were read to the participants one
at a time. A given participant compared each pair in one order only, hence
the NA's in ordered.pref.
The names were selected to fall within the upper (Tim, Lucas), mid (Michael,
Robin) and lower (Benedikt, Julius) range of the top 100 of the most popular
boys names in Germany in the years from 1990 to 1999
