A recent review of double-blind, placebo-controlled trials (n=10) (J Molina-Infante, A Carroccio. Clin Gastroenterol Hepatol 2017; 15: 339-48) showed that most individuals who consider themselves to have nonceliac gluten sensitivity (NCGS) do not show gluten-specific symptoms. Only 16% (38 of 231) showed symptoms specific to gluten ingestion. In addition, the authors describe a 40% nocebo response (similar or increased symptoms in response to placebo).
My take: Due to the absence of a reliable test for NCGS, there are a lot of people who avoid gluten when gluten is not the main culprit for their symptoms.
