Peter C. Gøtzsche, a co-founder of the Cochrane Collaboration, critically assesses the organization's trajectory, arguing it has experienced a significant decline in scientific integrity and ethical standards, particularly under former CEO Mark Wilson and current CEO Karla Soares-Weiser. Gøtzsche, who was expelled in 2018, details numerous cases of alleged editorial misconduct, censorship, and conflicts of interest. He highlights issues in reviews concerning influenza vaccines, DTP vaccines, HPV vaccines, antidepressant withdrawal, face masks, mammography screening, and Covid-19 vaccines. He claims Cochrane has prioritized institutional reputation, financial interests, and political expediency over robust, unbiased scientific evidence, often publishing misleading reviews or suppressing high-quality ones that contradict popular narratives. Gøtzsche concludes that Soares-Weiser's leadership failures in addressing these deep-seated problems indicate Cochrane's "sinking ship" status is beyond repair, attributing this decline to a pervasive "clubbiness" that compromises scientific objectivity.
