In their tween and teenage years, girls become dramatically less self-assured—a feeling that often lasts through adulthood.
The change can be baffling to many parents: Their young girls are masters of the universe, full of gutsy fire. But as puberty sets in, their confidence nose-dives, and those same daughters can transform into unrecognizably timid, cautious, risk-averse versions of their former self.
Over the course of writing our latest book, we spoke with hundreds of tween and teen girls who detailed a striking number of things they don’t feel confident about: “making new friends,” “the way I dress,” “speaking in a group.” In our research, we worked with Ypulse, a polling firm that focuses on tweens and teens, to survey more than 1,300 girls from the ages of 8 to 18 and their parents. (The sample was broadly representative of the country’s teen population in terms of race and geographic distribution.) The data is more dramatic than we’d imagined: The girls surveyed were asked to rate their confidence on a scale of 0 to 10, and from the ages of 8 to 14, the average of girls’ responses fell from approximately 8.5 to 6—a drop-off of 30 percent.
