Do anchoring effects underlie event-splitting effects? An experimental test

Starmer and Sugden (Journal of Risk and Uncertainty, 1993, 6, 235–254) and Humphrey (Journal of Risk and Uncertainty, 1995, 11, 263–274) report experiments investigating the event-splitting phenomenon in experimental tests of theories of decision making under risk and uncertainty. This paper reports a test of whether the anchoring and insufficient adjustment of probability assessments could underlie these findings and concludes that it does not.
