We hypothesize that uncertainty about the productivity of the public god leads to a decrease in the perceived impact of the contribution resulting in a lower contribution to the public good. We also hypothesize that this effect on the perceived impact is moderated by a general sense of powerlessness. We have performed an online experiment in which participants faced both a public good game with and without productivity uncertainty. Results showed that uncertainty decreased the contribution to the public good, but this effect was not explained by perceived impact nor a general sense of powerlessness. Interpretations and limitations of this research and suggestions for future research are discussed.Show less

The expectations were that higher generalized trust would be related to higher cooperation, and that this positive relationship would be even stronger when uncertainty about the cooperativeness of contributing would be introduced. The reasoning was that the environmental uncertainty would make the decision situation ‘weaker’ (i.e., vague or no cues for appropriate behavior in the situation), and therefore individuals would rely more heavily on dispositional traits. We tested this by presenting participants with public good games with and without uncertainty. While the first expectation was met, the results did not corroborate our reasoning of the second expectation. Thus, generalized trust proved to be a stable predictor for cooperation. However, it did not become stronger when uncertainty about the cooperativeness of contributing was introduced.Show less

It was predicted that induced self-uncertainty would increase brand preference for national over international brands. Furthermore, it was predicted that this effect of the induced self-uncertainty would be especially true for participants with low NFC and less so for participants with high NFC. In total 141 Dutch participants filled out the online questionnaire. Based on an ANOVA and a moderation analysis it was concluded that neither the condition nor NFC, had a significant effect on brand preference. Lastly, no significant interaction effect was found as well. However, the manipulation check revealed no difference in self-uncertainty between groups. To conclude, NFC did not affect brand preference, and further research is needed to explore the role of self-uncertainty in brand evaluation.Show less
