Janet K: I agree with you Mariana that subjective observations are useful – extremely useful, but they are not experiments. This was supposed to be an objective experiment rather than a subjective observation and it did not have the controls that should have been part of it. They came to a result on the subject of whether a certain behaviour was similar in dogs and people by examining the dogs’ behaviour but not the humans’. I was also saying that there are two biases that are dangerous: assuming that humans are more unique than they are and assuming that humans are less unique than they are.
