idoser is literally binaural beats
Here's how idoser works.
1. You want to get high.
2. You buy iDoser stuff thinking it will make you high.
3. The fact that you want to get high and the natural need to validate the time or money into purchasing or acquiring iDoser tracks work together to convince you that you are high.
4. You think you're high purely through the power of suggestion.
There was a study where people were given various nonalcoholic beverages and were told they were alcoholic. Lo and behold, these people started to act drunk despite consuming no alcohol.
Becoming high is 100% a chemical process. If you're not consuming some kind of drug you will not get high. We're assuming "high" is specifically referring to the feeling of a drug induced high, not runner's high or something. Binaural beats may have something to them. Maybe you can feel sad or anxious by listening to particular sounds, musicians have been exploiting this for hundreds of years. There is nothing to suggest that you can induce a high by listening to some randomly generated noise, and if you're going to fall for it then you might as well start stocking up on magnetic healing bracelets and cleansing Japanese foot pads because they're just as effective at what they do.
In fact, in the Wikipedia article you link to, iDoser is all but specifically named in the unverified claims section. Binaural beats themselves do not necessarily make you study better, get high, or diet. You convince yourself that these are working, and as a consequence, you actually DO study better and concentrate harder. But it's purely by tricking yourself. I could give you a sugar pill and tell you that it would make you study better, and if you actually believed it worked, you would actually study better.
If you think iDoser is working, it's purely through the power of your mind. Please, by all means, go on believing it works, because the second you stop believing it works it won't work. We wouldn't want your investment to go to waste.
