Background Noise Affects Taste of Foods 79

Posted by samzenpus from the that-sounds-delicious dept.
gollum123 writes "The level of background noise affects both the intensity of flavour and the perceived crunchiness of foods, researchers have found. Blindfolded diners assessed the sweetness, saltiness, and crunchiness, as well as overall flavour, of foods as they were played white noise. While louder noise reduced the reported sweetness or saltiness, it increased the measure of crunch. It may go some way to explaining why airline food is notoriously bland — a phenomenon that drives airline catering companies to season their foods heavily. In a comparatively small study, 48 participants were fed sweet foods such as biscuits or salty ones such as crisps, while listening to silence or noise through headphones. Also in the group's findings there is the suggestion that the overall satisfaction with the food aligned with the degree to which diners liked what they were hearing — a finding the researchers are pursuing in further experiments."

Meta-Research Debunks Medical Study Findings 261

Posted by Soulskill from the truthiness-in-medicine dept.
jenningsthecat writes "From The Atlantic comes the story of John Ioannidis and his team of meta-researchers, who have studied the overall state of medical research and found it dangerously and widely lacking in trustworthiness. Even after filtering out the journalistic frippery and hyperbole, the story is pretty disturbing. Some points made in the article: even the most respected, widely accepted, peer-reviewed medical studies are all-too-often deeply flawed or outright wrong; when an error is brought to light and the conclusions publicly refuted, the erroneous conclusions often persist and are cited as valid for years, or even decades; scientists and researchers themselves regard peer review as providing 'only a minimal assurance of quality'; and these shortcomings apply to medical research across the board, not just to blatantly self-serving pharmaceutical industry studies. The article concludes by saying, 'Science is a noble endeavor, but it's also a low-yield endeavor ... I'm not sure that more than a very small percentage of medical research is ever likely to lead to major improvements in clinical outcomes and quality of life.' I've always been somewhat suspicious of research findings, but before this article I had no idea just how prevalent untrustworthy results were."
