You disgust me <| sep |> mommy wont let him use her credit card probs <| sep |> It ' s not about whether those people know what they ' re talking about or even if they ' re experts . The placebo effect is very real and affects basically everyone , other studies haven done brain scans while the subjects drink cheap wine they ' re told was expensive and the pleasure centre of the brain lit up like crazy , these people weren ' t lying they actually enjoyed the same wine more when told it ' s better . Most of the wine studies just confirm what we already know , humans are subject to bias , and it effects how they perceive things . That ' s why medical studies have control groups and even the administering doctor doesn ' t know if the patient is receiving the actual medication .
