When evaluating the negative group effects, we
asked the participants whether they exerted less effort
for their idea because they knew that they were being
supported during their creative stage (addressing freeriding
and dispensability of effort) and whether they
exerted less effort because the outcome might not only
be their work. The majority answered that they
strongly disagree (p=6) and disagree (p=7) that they
exerted less effort due to knowing about the support.
The same results were obtained from the second
questions (CEM). Six participants strongly disagreed
and eight participants disagreed that they exerted less
effort, because they expect their effort not to be
attributed to themselves alone. The following table
shows the questions for the second part of our
hypothesis regarding the negative group effects
