The purpose of the present investigation is to analyze the relation of frustration tolerance and delay of gratification with PhD-intention and expectations. We conducted one correlational and two experimental studies. In Study 1 (N[subscript 1] = 171 undergraduates), we found the hypothesized positive association between delay of gratification and frustration tolerance and the intention to obtain a PhD. In Studies 2 and 3, we used experimental vignette designs. In Study 2, doctoral students and postdocs (N[subscript 2] = 180) evaluated a fictitious student regarding PhD-intention and a successful PhD-process. As expected, students with high gratification delay and frustration tolerance were judged as more likely to start and complete a PhD than students described low in these volitional traits. In Study 3, we contrasted Study 2's findings by asking employees of the private sector (N[subscript 3] = 150) to rate the same students' intention to join a company instead. None of the factors influenced participants' judgments when it comes to a non-academic career track.
