My Main Independent Variable...Whoopee!

So my dissertation project relies on a survey that people have been using for years. But what do you guys make of study with the following features:

1) Leaves out crucial data in the published data set, making replication impossible
2) Results change when statistical method changes
3) Leads to implausible conclusions
4) Doesn't correlate with other, similar data
5) Uses retrospective self-reporting
6) Plugs in the mean to fill in missing data

Sounds great, doesn't it? I know I'm thrilled about it!
