      "heading": "The mental boundaries of a decision",
      "point": "Daniel Read, George Loewenstein and Matthew Rabin (1999, Journal of Risk and Uncertainty) examine “choice bracketing”: considering choices separately or as part of a set."

      "heading": "The premature conclusion",
      "point": "One might conclude that decisions should always be made separately to avoid excessive diversification."
