James C. Coyne

[4] Coyne was named an ISI Highly Cited Researcher by Clarivate Analytics in 2001, and was ranked #200 in a 2014 list of the most eminent psychologists of the post-World War II era.

[7][8] A 2007 study led by Coyne found that positive emotional well-being was not associated with increased life expectancy among head and neck cancer patients.

[14] Coyne has stated that a 1970s study by Ellen Langer, which found that elderly people given plants to take care of lived longer than those who were not, would not have "much credibility today, nor would it meet the tightened standards of rigor.

"[15] Coyne has also criticized studies that claimed to have shown that acceptance and commitment therapy was effective in reducing rehospitalization in cases of psychosis.

[17][18] Coyne pointed out that as part of Oettingen's aggressive promotional campaign for her book, her own son created Wikipedia articles about her work.
