Fredrickson responded to the critique by agreeing that Losada's mathematical modelling is "questionable" and does not show that there are precise values of the ratio, but also arguing that the evidence for the benefits of a high positivity/negativity ratio is solid. Fredrickson noted that Losada declined to respond to the criticism. Sokal was openly critical about this partial retraction, and in 2014, "American Psychologist" published their response to Fredrikson's retraction, where they emphatically argue that there is no evidence for the critical positivity ratio whatsoever. Responding to comments on their original critique, they conclude the entire affair by lamenting that instead of replacing the "unbridled romanticism" of humanist psychology with a rigorous evidence-based psychology, as Seligman and Csikszentmihalyi promised in their founding manifesto of positive psychology, the widespread acceptance of the critical positivity ratio shows, in their view, that positive psychology has betrayed this promise: "That the sin is now romantic scientism rather than pure romanticism is not, in our view, a great advance."
