- Evidence limits
- Adjacent research, not a directly sampled family-office study. Applicability to a family office requires separate assessment. However, our study has several limitations. It reveals that online lab-in-field experiments suffer from strong homogeneity of the target audience of online platforms. The self-selection of participating in the experiment amplifies this limitation, as it can introduce correlations between causally unrelated background variables that co-determine a participant’s susceptibility to positive emotions and willingness to donate. This effect could exacerbate ceiling effects that lead to null results, as observed in the present case. In principle, this problem can be mitigated by another feature of online experiments: the low or zero marginal costs of increasing the sample size [47]. In practice, however, this is not as simple as in theory because limitations exist in the number of potential participants: green crowdfunding platforms are still, for the most part, niche services, and they do not attract millions of visitors.
