Our research showed that as a person gets older, their Tolerance of Ambiguity also increases. For overall TOA total scores, Baby Boomers (born 1946 to 1964) were significantly higher than both Gen X (born 1965 to 1980) and Gen Y (born 1981-2000). Gen X was significantly higher than Gen Y. The same pattern was found with Comfort with Ambiguity (i.e. Baby Boomers were most comfortable, followed by Gen X) and for Managing the Uncertainty. There were no generational differences in Desire for Challenging Work.
