I often tell people that I love my dog more than any human has ever loved a child, but I don't love this study. The result is fairly obvious to any dog owner, but the study is representative of the type of "pop" science that appears so often in the news but carries little actual significance. 34 dogs total, 17 in each group (humming vs crying), 9 of which respond to humming and 7 of which respond to crying, albeit the latter much faster than the former. Of those 34 dogs, 16 were therapy dogs. While the time difference is large, more dogs respond to humming than crying. So we have a very small sample size which is biased towards therapy dogs. It is also very susceptible to p-hacking. Why "Twinkle Twinkle Little Star"? Was this the song that produced the largest effect out of 20 different songs? Why do more dogs respond to the humming than crying but the dogs that do respond to crying act so quickly? Were the crying sounds much louder than the humming? Why not crying vs yelling, both of which are likely of similar volume? And so on. |
