Why is it hard to get scientific evidence of the paranormal?? . . . some of my thoughts . . .
IMO paranormal events are unpredictable and not reproducible so usually defy any research attempt requiring such traits . . . however, this doesn't preclude research based on data collection and descriptive categorization as is common in cultural anthropology and primatology . . . one needs to first collect descriptive testimony and correlate it possibly with environmental data as in chronobiology ( [link to en.m.wikipedia.org
] for example the Federal Reserve found a stastically valid correlation between solar storm activity and transaction activity on the securities market . . .
We now have massive data collection and analysis capabilities never before realized . . . we need to be more imaginative in how to capture and describe the events and look for commonalities, trends, and correlations of location, date, environment, relationships, genetics and so forth . . .
In other words . . . standard research approaches are not likely to be successful until more is understood on how the interaction of membranes and multi-universes work but descriptive collection and categorization of paranormal events and data analysis may lead to surprising relationships . . .
