I often have that feeling after reading Reuters "news" and books by liberals and listening to speeches by Dems. Seemed to me that they were intentionally plotting to bewilder people into submission. But perhaps I do the Rats an injustice. After all, the article goes on to state:
Rats and pigeons, though undeniably clever, don't seem to know when they don't know.
In other words, both dolphins and humans know "what we don't know" and know how to learn more.
Bateson called it "second-order learning," and only humans and dolphins are know to possess that faculty.
