 Another group of researchers suggested to modify or restrict the Ramsey test. Solutions of this kind were discussed, amongst others, by Rott (1986), Gärdenfors (1987, 1988), Levi (1996: Chapter 2), Lindström and Rabinowicz (1998) and Nute and Cross (2001). Arguably, none of these adaptations of the Ramsey test has retained the intuitive appeal of the original idea.
