  • 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.







  • This is a solved issue. Use a bit set to have the different heads you need to fit on one driver. You can get ones that store the bits inside the driver.

    Any telescopic mechanism is going to have a hollow centre and be weaker and prone to deforming. Larger hex keys are used to deliver more torque, making them hollows defeats the purpose of having a larger key, and small bolt and hex key should have been used to save weight and cost (or the same size to standardised the tooling).
