But we are happy to agree with Hämäläinen et al. that the central flaws in Fredrickson and Losada (2005) and its predecessor articles are logical and conceptual, not narrowly mathematical. And they are, as we have demonstrated, overwhelming. The original rebuttal authors conclude this salvo by lamenting that the "unbridled romanticism" of which humanist psychology has been accused has not been replaced with a rigorous evidence-based psychology—as Seligman and Csikszentmihalyi promised in their founding manifesto of positive psychology—rather, the widespread acceptance of the critical positivity ratio shows that positive psychology has betrayed this promise, stating that "the sin is now romantic scientism rather than pure romanticism is not, in our view, a great advance." J. Humanist. Psychol. special issue, and other follow-up As of January 2014, as Andrew Anthony notes from his preparation for his article in The Guardian from that period, Fredrickson continued to maintain "on empirical grounds" that "tipping points [in relation to positive emotions and flourishing] are highly probable", as communicated to him via email. In 2018, the Journal of Humanistic Psychology published a special issue focused on the aftermath to the rebuttal of the original Fredrickson and Losada article, where Harris L.

Anthony also noted that following the Brown-Sokal-Friedman rebuttal, Fredrickson has "removed the critical chapter that outlines Losada's input from further editions of Positivity", and that she has largely avoided engaging the popular press. Reporting from a variety of sources, including The Chronicle of Higher Education and The Scientist, the fact that the problems with the
