A critical examination of 360 degree feedback: its murky origins, thin evidence base, and the ways it can undermine the very honesty it promises. Traces the practice from officer selection in the 1930s German Reichswehr to its 1980s trademarking by an assessment firm, noting that attempts to trademark a practice should raise a red flag. The evidence is strikingly weak for something so embedded: the Institute for Employment Studies concluded adoption reflects 'faith rather than proven validity', and the authoritative 2005 meta-analysis (Smither, London & Reilly) found performance improvements 'generally small', with little new research since even as usage climbs. Develops several psychological-safety-relevant critiques: averaging many biased ratings doesn't cancel bias but blends it into something smoother and harder to attribute, with gender and racial bias accumulating behind a falsely objective aggregate; the forms ask how a person is performing but rarely about the pressures and constraints they faced, so the individual ends up holding the weight of the system around them; and a formal annual feedback mechanism exerts a gravitational pull that suppresses the ordinary, low-stakes, day-to-day feedback that actually helps. On anonymity: it can't be shortcut to safety — what people need is consistent, lived experience that speaking honestly won't cost them, which an anonymous form cannot manufacture. The deeper point is that candid feedback isn't a system you install.
