  • This is a common misconception of the placebo effect. The placebo effect is a measurement issue, not an actual benefit.

    Tests are corrupted by using the reposnes and judgement of humans. People will say they had some sort of benefit because of expectations, poor recollection and politeness. It doesn’t mean a benefit was gained. A placebo group allows researchers to quantify how much the placebo effect has on the data they gathered, they can then see if the experiment they did had any effect. Placebo is literally our definition of zero effect.

    Anyone telling you placebo is a good thing is wrong, misinformed or deliberately misleading you. In many countries it is illegal for doctors to prescribe ‘placebo treatments’. They will still recommend such things to their patients - not because they work but because they get the patient out the door and less likely to come bother them again.





  • America tried to modernise many British means of methods and standards. They used a metric currency long before Britain. That’s why they have a cent (1/100) rather than pennies and bobs and truppence.

    They got ride of many terms for multiples of measurements that made the imperial system more similar to metric. Americans use ounces, but they don’t use pounds.

    America also defines their us customary units using metric. There’s no longer an inch. There is a meter and from that an inch is defined as 24 millimeters. This is largely due to British, Canadian and American components for fighting wars not fitting together despite all using the same inch.

    Had America modernised a little later they probably would have converted to metric earlier than Britain.


  • The intro to the Wikipedia article on placebo is quite good. Lots of easily accessible sources often misrepresent the placebo effect. The Wikipedia article does suggest placebo effect improves pain response, but it does say perceived.

    If someone says something uses the placebo effect it means it doesn’t work. They may not know that. But a placebo response is our measure for medical treatments that don’t work.

    When people say the placebo effect works it’s like a microwave that doesn’t heat food. People hear the ding and tell you the food does feel warmer. The perception is that the broken microwave heats food, but the food isn’t any warmer. We avoid this issue in science by making measurements, but for fields like medicine we often rely on people saying how they feel. This is how the placebo effect corrupts medical studies. People are very unreliable. They also often want to be polite and say they had a positive effect from the treatment. This is doubly so for people that volunteer or buy these types of herbal treatments. They think only idiots would buy or take these things that don’t work, I’m not an idiot so the treatment must be working.

    I didnt bother reading the second since the first was blatantly misleading.

    The second looks like they’re trying to p hack hack their way to a result.

    They also have more relapses in the curicumin group in the second 6 month period than the control group. They also have enough people leaving the control group to cause a shift in their p value to make their results insignificant.

    The second papers findings are weak and they aren’t very robust.

    The evidence is much better for SSRI, and it isn’t great, but the referred paper even points out that the curriculum wasn’t as effective as an SSRI.

    The meme remains true, no proper or valid studies exist. The existence of a paper doesn’t prove that, the paper is self addresses it wasn’t a proper study. They just did it in a dishonest way.

    This study is absolutely terrible.

    The study found no differences in the first four weeks. More than 10% dropped out during the study. The study was too small a sample to draw any serious conclusions from. The conclusions they did draw from were a subsample of people they declared treatment resistant. They even say in the paper their isn’t enough data to suggest their was any benefit, just not forcefully enough. Just enough to make low information readers think the study was successful.

    This study was done in response to two other studies. One which showed no benefit another that suggested a benefit, but the study lacked a control group. So no meaningful conclusion could be drawn.

    Finally the researchers were funded by ‘health supplement’ groups.

    The placebo effect doesn’t help. It’s just noise in the data collection process. It’s particularly problematic with human trials that rely on subjective evidence. Humans have a bias that actions have effects, even when they don’t (gamblers blowing on dice, wishing on a star etc).

    Any intervention will have people think that the outcome has changed because of the intervention. This doesn’t mean the placebo effect helped, it just altered the recorded outcome. If it was a device was used to make the measurement, rather than human opinion, we just call it noise/error.

    It’s a common misconception that the placebo effect does something. It does nothing other than artificially increase subjective measurements. Placebo effect is stronger in very subjective medical conditions such as pain, shiny packaging and brand names are reported to provide greater pain relief. Such medicines are so tightly regulated the formulation and supply leaves very little opportunity for medicines to actually have an effect. You don’t see the same effect when it comes to reducing the size of cancer tumours or altering directly measurable quantities.

    Doctors aren’t allowed to prescribe placebos in the UK. Because it’s dangerous and a source of corruption. Such as King Charles selling homeopathic services to the NHS. Doctors do recommend such services, they do this primarily to dismiss patients and their issues.



  • They could attempt to quantify how gamed the result is and reduce its ranking. Also punishing domains with lower ranking the more they return SEO optimised pages. They could also increase the ranking of older pages.

    This doesn’t really help google, it only really improves their search results. Google wants these hyper SEO optimised results with lots of advertising. Additionally, the less relevant the result is the more searches a person does. Each search is an additional set of ad impressions.

    Google search is better than ever. Because it generates more advertising opportunities for google. Google isn’t in the business of returning good search results, they are in the business of displaying ads.
