Now, it's true -- scientists often push back at me, and they'll say, "Ah, look, the animal might be stressed, or maybe the animal's just confused because his or her routine has been disrupted."
C'est vrai, les scientifiques rétorquent souvent : « Regarde, l'animal est peut-être stressé ou tout simplement confus parce que sa routine a été perturbée ».
