I always wondered that whenever such reports or surveys come out why don't these organisations make the whole data and methodology public? Are they afraid that if they made it public, people will know how muddy these waters are?
When they don't release the data and/or methodolgy, you have to treat the result the same: garbage.
They could be completely making up data or demonstrating the gold standard example of pristine data collection and brilliant analysis but we'd never know.. and for some reason, they don't want to tell us.
I'm quite confident on why they don't want to share their data and/or methodology but there could be legitimate reasons and I want to be open to those.
Regardless, without that information, we can only evaluate them based on how rigorus they've been in the past:
Are the researchers and organizations involved known for effective data collection and solid analysis?
