Clear evidence of unreliability, duplication, plagiarism and unethical research are all valid considerations for retracting a paper, but “concerns” are not according to the very retraction guidelines BMC says it follows. Such considerations do not include “undeclared competing interests” either. Although alerting readers to such non-disclosures may serve as a purpose of a retraction according to COPE, they are not justification for a retraction.
BMC’s retraction of Dr. Hooker’s paper is only the latest of policy breaches by the publisher after it deleted his article from its website in breach of policy on the permanency of articles. Citing a then-pending investigation, BMC refused to comment on that violation when contacted by Autism Investigated. Now with the paper retracted in breach of yet more policies supposedly followed by BMC, the publisher has even more explaining to do.
