Belief in Good Luck (BIGL) review


Scale name: Belief in Good Luck (BIGL)

The authors wanted to reliably assess irrational beliefs about luck and examine the beliefs in relationship to expectations of success. Early psychometric properties support the scale as a useful assessment of luck.

Author's summary of findings (pp. 486-487).

This is generally in agreement with previous findings suggesting that people who believe in personal good luck react to lucky events by becoming more positive about the likelihood of future success (Darke & Freedman, 1997). In general, it is suggested that irrational beliefs about luck can serve as a source of positive expectations for the outcome of future events.
