We examine critically the claims made by Fredrickson and Losada (2005) concerning the construct known as the "positivity ratio." We find no theoretical or empirical justification for the use of differential equations drawn from fluid dynamics, a subfield of physics, to describe changes in human emotions over time; furthermore, we demonstrate that the purported application of these equations contains numerous fundamental conceptual and mathematical errors. The lack of relevance of these…

The persistence of wishful thinking.
TLDR
In response to a critique, Fredrickson and Losada withdrew their nonlinear dynamics model, but Fredricks on (December December 2013) reaffirmed some claims concerning positivity ratios on the basis of empirical studies and the alleged supporting evidence is reviewed.
The Persistence of Wishful Thinking: Response to “Updated Thinking on Positivity Ratios”
We analyze critically the renewed claims made by Fredrickson (2013) concerning positivity ratios and “flourishing,” and attempt to disentangle some conceptual confusions; we also address the alleged
Implications of Debunking the “Critical Positivity Ratio” for Humanistic Psychology: Introduction to Special Issue
An extraordinary claim was made by one of the leading researchers within positive psychology, namely, there is a universal–invariant ratio between positive to negative emotions that serves as a
Updated thinking on positivity ratios.
TLDR
Even when scrubbed of Losada's now-questioned mathematical modeling, ample evidence continues to support the conclusion that, within bounds, higher positivity ratios are predictive of flourishing mental health and other beneficial outcomes.
Nonlinear Dynamical Systems and Humanistic Psychology
The recent debunking by Brown, Sokal, and Friedman of some high-profile results applying chaos theory to positive psychology creates the opportunity to shed light on the quality work that has been
There Is No Empirical Evidence for Critical Positivity Ratios: Comment on Fredrickson (2013)
Fredrickson and Losada (American Psychologist, 2005, 60, 678-686) theorized that a ratio of positive affect to negative affect (positivity ratio) of 2.9013 acts as a critical minimum for well-being.
An empirical ratio in search of a theory.
TLDR
This comment shows how to account for the phenomenon of the 3:1 ratio using a mathematical model of reflexive awareness that captures the property of the mind to model self and other at increasing levels of awareness.
No empirical evidence for critical positivity ratios.
TLDR
It is pointed out many times over many years that the data and the analysis used to test a theory should correspond to that theory and that a test of a within-person theory nearly always requires within- person data and analysis.
Nonlinear dynamical models in psychology are widespread and testable.
TLDR
Comments on the article by Fredrickson and Losada about nonlinear dynamical systems (NDS) models in psychology that would-be researchers should understand if the goal is to move the science forward are offered.

TLDR
Findings suggest that a set of general mathematical principles may describe the relations between positive affect and human flourishing.

The success of the ideas of chaos has led to attempts to apply them to a great variety of situations. This is in principle a good strategy, but the results are not always up to expectations. In some

TLDR
The logistic map, a canonical one-dimensional system exhibiting surprisingly complex and aperiodic behavior, is modeled as a function of its chaotic parameter, and the progression through period-doubling bifurcations to the onset of chaos is considered.
