Most Hindawi journals do not have editors-in-chief, but rather have editorial boards consisting of staff and a volunteer board of 30 to 300 scholars. There is some concern that this style may lead to lower quality output, or at least the potential for it. However, journalist Poynder states, "there is no evidence that Hindawi's editorial approach, or the way in which it recruits authors, has had any serious consequences so far as the quality of its papers is concerned," although he notes that some articles contain poor copy-editing. At least one Hindawi journal ("Pain Research and Management") has an editor-in-chief.
