What Clever Hans and sniffer dogs have in common

[DuB]

A interesting study just came out providing evidence that trained drug- and explosive-sniffing dogs frequently give signals in response simply to the trainer's expectations, regardless of whether drugs or explosives are actually present. Details here: Clever hounds Turns out that even the hounds will profile you.

Ergo, dogs are smart than humans But it is also a well known fact that they train the dogs to react to the handlers signals to purposely bark or sit to indicate drugs or explosives even if the dog doesn't detect it. EDIT: *smartER* lmao
