 It was noted in  Section 1  that John Maynard Keynes rejected predictivism—he argued that when a theory T is first constructed it is usually the case that there are reasons R that favor T. If T goes on to generate successful novel predictions E then those reasons combine with R to support T—but if some \(T'\) is constructed ‘merely because it fit E’ then \(T'\) will be less supported than T. This has been deemed the “Keynesian dissolution of the paradox of predictivism” (Barnes 2008: 15–18)
