In this first episode, the class of seven year-olds are tested across a range of important psychological measures. Doctor Javid is shocked by the results, which are enough to convince class teacher Mr Andre to eradicate from the classroom anything that reinforces the idea that boys and girls are fundamentally different; from the books they read, to the way he speaks to them. The children meet a group of professionals who challenge their ideas about what jobs men and women can do, and later take part in a game designed to test their strength and their expectations of what they can achieve.Meanwhile, Doctor Javid observes what happens to a group of adults unknowingly playing with babies who have had their clothes swapped with the opposite gender.
