"Reverse Scientific Method:
1)Draw your conclucion.
2)Select data,no matter how flawed,to support you conclusion.
3)Discard any data,no matter how valid,which does not."
There are a number of scientific discoveries based on this approach. You might be surprised by that, but brilliant men knew what the principle should be and when the data didn't fit they found reasons why it didn't fit. So they didn't throw away good data, but bad data in order to get to the truth. Sometimes this method is needed to have progress, although before you publish the results you go back and redo the study the correct way.
The scientific method says nothing about how you come up with a theory or hypothesis. You can use taro cards and still follow the scientific method. What is important is that you devise and carry out a proper experiment. Good scientists often have an intuitive knack for insights into bad results but good luck getting confirming results from those taro card theories.
