Summary
Drug companies often send gifts to physicians when marketing their products. Most physicians believe that their choices when prescribing drugs are not influenced by drug companies’ gifts. However, most physicians also believe most other physicians’ prescription choices are influenced by such gifts.
Notable Valid Inferences
The two beliefs described can't both be true. Either at least some physicians who think that their choices aren't influenced by gifts actually are influenced by gifts, or the physicians who think most other physicians are influenced by gifts are wrong.
