Comments on the article by Fredrickson and Losada (see record 2005-11834-001). Recently the current authors (Brown, Sokal, & Friedman, 2013) debunked the widely cited claim made by Fredrickson and Losada (2005) that their use of a mathematical model drawn from nonlinear dynamics (namely, the Lorenz equations from fluid dynamics) provided theoretical support for the existence of a pair of critical positivity-ratio values (2.9013 and 11.6346) such that individuals whose ratios fall between these…

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.
Positive psychology and romantic scientism.
It is hoped that the revelation of the problems with the critical positivity ratio ultimately demonstrates the success of science as a self-correcting endeavor, but it would have greatly preferred it if the work had not been necessary in the first place.
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
Positive ratios revisited: reports of the theory’s death have been greatly exaggerated
ABSTRACT The states of mind (SOM) model-related ratios of positive/negative affect to psychological functioning, findings that were later integrated into Lefebvre’s mathematical model of
Positive Psychology’s A Priori Problem
The positive/negative distinction works well in many fields—for example, in mathematics negative numbers hold their own, and in medical pathology negative results are usually celebrated. But in
The optimism-pessimism ratio as predictor of employee creativity: the promise of duality
Purpose The purpose of this paper is to study if the employees’ optimism-pessimism ratio predicts their creativity. Design/methodology/approach In total, 134 employees
Best-Practice Guidelines for Positive Psychological Intervention Research Design
Positive psychological interventions (PPIs) have been subjected to considerable criticism in recent years. Following similar movements across other domains of psychology, attempts to replicate
On reproducibility and replicability: Arguing for open science practices and methodological improvements at the South African Journal of Industrial Psychology
Problematisation: In recent years, psychology has been going through a crisis of sorts. Research methods and practices have come under increased scrutiny, with many issues identified as negatively
Collaborative pursuit of flourishing
This research explored two under-researched core positive psychology constructs: flourishing, and positive or enabling institutions, using twin methodologies: appreciative inquiry and case study
Set points of positivity ratio for different levels of well‐being: A latent profile analysis
Previous studies have explored the set points of the positivity ratio by grouping according to predetermined cut-off scores, resulting in inconsistent criteria and unstable results. This study


The complex dynamics of wishful thinking: the critical positivity ratio.
It is concluded that Fredrickson and Losada's claim to have demonstrated the existence of a critical minimum positivity ratio of 2.9013 is entirely unfounded and is urged to exercise caution in the use of advanced mathematical tools, such as nonlinear dynamics, and in particular to verify that the elementary conditions for their valid application have been met.
Updated thinking on positivity ratios.
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.
Positive affect and the complex dynamics of human flourishing.
Findings suggest that a set of general mathematical principles may describe the relations between positive affect and human flourishing.
Optimism predicting employees' creativity: The mediating role of positive affect and the positivity ratio
We examine how optimism predicts creativity both directly and through the mediating role of positive affect and the positivity ratio (the ratio between the frequency of positive and negative
The Role of Positivity and Connectivity in the Performance of Business Teams
Connectivity, the control parameter in a nonlinear dynamics model of team performance is mathematically linked to the ratio of positivity to negativity (P/N) in team interaction. By knowing the P/N
The Positivity Ratio and Functioning Under Stress
The positivity ratio reflects the ratio of positive affect to negative affect. In two studies, the authors investigated the relationship between positivity ratio and functioning under stress. Study 1
The ratio between positive and negative affect and flourishing mental health across adulthood
Although the data supported the notion of a positivity ratio of 2.9 as a ‘critical value’ in young adulthood, this value did not equally well discriminate the mental health status of middle-aged and older adults.
