I have a few relatives that believe that "The Secret" (Law of attraction) works. I don't think it works. So, all parties involved in the debate are currently heavily biased.
So what I'd like to do is come up with a simple unbiased scientific test for them to try to see if it works or not. I'll explain the test below and I'd like some feedback about my proposed test so I can make sure I'm not missing anything. I'd also like to be able to explain why "The Secret" seems to work because of confirmation bias and I need some help with those terms and definitions in the context of "The Secret".
The test
I will generate with a pseudo-random number generator (because I'm a software engineer geek) a list of 30 pseudo-random values before the test begins. Each value will be either "Positive" or "Negative/Neutral". Each value represents one day (or other unit of time agreed upon) and the test subject will think positively on each day that has a "Positive" next to it, and will either not think about it or think negatively about it on each day that has a "Negative/Neutral" next to it. Each day, the level of success will be recorded. Success must be measured objectively (e.g. amount of money made/lost, number of free bicycles that appear, etc.). The Success or Failure must not be affected directly or indirectly by the test subject (e.g. consciously or subconsciously working harder to market an Internet product on the positive days than they do on the negative days and then counting income from those sales as their success/failure) - it has to be something that is not related to the test subject. At the end of 30 days (or 30 hours, or whatever), I will average the positive and negative days' success/failure results and calculate the standard deviation and see if there's a statistically significant difference between positive thinking and negative thinking days.
Help
1. Did I miss anything in the process or requirements? I wrote them in paragraph form - is there a more scientific form of writing it to make it more easily expressed in a standard way?
2. Is calculating the mean and standard deviation all that would be required to analyze the result and derive a conclusion from it? Do I need to calculate the standard error? Help me out on the statistical requirements needed to show significant difference or not.
3. Confirmation bias is when a person more easily accepts things that match their existing beliefs while being skeptic of (or ignoring) things that don't match their preexisting beliefs, right? This would apply to people who already believe in "The Secret". There's also the issue of remembering the days it worked well and forgetting the days it didn't. Is that behavior also called confirmation bias or does that have a different name?
4. Any other help in setting up and executing the test or explaining the results of the test and why people seem to think it works when it really doesn't would be appreciated. In fact, it would be nice to have them give me a subjective answer to whether they thought "The Secret" worked during those 30 days at the end of it and compare that subjective answer to the objective data and then use the confirmation bias and other explanations to explain the discrepancy.
Thanks in advance for all of your input. In fact, if we could get this test nailed down, we could then have "believers" and "skeptics" run the test whether they be members of the forum (skeptics) or friends of members of the forum (believers) to run the test and post their results.
