If you want to actually be clever then the only option is to sample all of the information available.

Limiting oneself to a subset of information is not how one makes an informed decision.

Reading every possible review of a product I'm considering sounds far less clever than a simple heuristic to me.

Pay attention to my words. I said to sample all of the data.

I didn't say anything about reading every possible review. But you do need a good, rounded sample.

All of the available information includes information about which information is safe to ignore.

Which is why I said you're supposed to sample all of the available data.
