This controlled experiment shows that false-feedback about sleep, in the absence of objective sleep differences, biases appraisal of daytime symptoms. This confirms a potential pathway in the development and maintenance of insomnia but also has important implications for wearable devices that claim to measure “objective sleep”, yet provide inaccurate data relative to gold-standard measurement.
