Now this seems like a silly study, and a silly assertion to make.
Toronto University says teaching childen with animal characters like Mickey Mouse can make children less intelligent.
Reading books that show animals talking or wearing clothes leads youngsters to think animals are like that in real life, claimed psychologist Professor Patricia Ganea.
This affects a child's ability to learn real facts in general and their knowledge of animals and the natural world in particular, she said.
I don't know ... we've all been shown characters like Mickey Mouse and Winnie the Pooh for years. Were we robbed of some intelligence? Let me know what you think in the comments below.
