Yesterday, I released a new episode of The Screenagers Podcast titled From Junk Food to Social Media: How Teens Get Manipulated.
In it, David Yeager, PhD, a psychology professor at the University of Texas at Austin and a well-regarded scientist in mindsets and motivations trained under the pioneer of Growth Mindset theory, Carol Dweck, discusses a recent study that examines how youth’s desire to use social media is impacted when they learn how companies are explicitly trying to manipulate them.
This is an excerpt from the episode where Yeager shares one of his groundbreaking studies, in which kids chose to eat 30% fewer sugary foods in school cafeterias during lunch because of the intervention they did. What’s really interesting is that this 30% drop lasted for several months after the intervention!
David’s interventional studies focus on harnessing children's and teens' values, such as wanting autonomy and caring about social justice, to help them make healthier and wiser choices in their lives.
David says,
“A lot of people think teenagers are like in one ear out the other, but that's not what we think. If you change what someone believes about a company, that sticks with them. You don't really need to be reminded of that, especially if it's egregious or hypocritical or harmful.”

So what about influencing the mindsets of youth regarding social media by looking at some of the negative issues associated with some companies?
Here is the section of the podcast in which David discusses Brian Galla’s work on this topic.
“Yeah, so some new research is really promising. It's applying this idea of values alignment, of aligning healthy behavior with Values like autonomy and concern for social justice, to the social media context. So in a way that's very similar to the tobacco companies’ market to children and how food companies make hot Cheetos addictive to children.
Social media companies have also marketed their products to children and made them have this neural reward that is very addictive. In a promising study led by Brian Gala, they've looked at whether you can make this same kind of argument. about the social media companies.
Brian Gallo and his colleagues ran an experiment where there were two groups. In one group, they got an exposé about the practices of the social media companies that cause young people to continue to want to revisit and scroll through every day, to grab their eyeballs for attention to make money. In another group, they got neutral content that did not inform young people of social media.
Then, they compared the social media use of those two groups over time. What types of things were students told about the way social media platforms are designed? It's designed to make you feel like you're It's never enough. You don't measure up. And also that you're going to miss out on your whole social life if you're not constantly checking up.
And that's exploiting everything that we've learned about the adolescent brain and how it processes reward and so on. Those design principles cause the applications to be addictive. And when you tell teenagers about that, they say, ‘That actually seems right to me.’ And they really respond negatively.
They say, “This is not how I want to spend my time. This is not how I want to be.”
After young people read the exposé about the social media companies’ practices they were more motivated to put down their social media and to use it less. Three months later, they had different attitudes about social media and they were more aware of these manipulative practices in the applications."
This podcast episode is a fantastic one to listen to with the youth in your life, or you can recommend that they listen to it on their own.

When kids break a rule, most parents default to handing down a consequence. But research on autonomy-supportive parenting shows that inviting kids to help decide the consequence leads to deeper learning, stronger accountability, and even kinder behavior toward others. Younger kids tend to overpunish themselves while teens often go easy, and both create natural openings for parents to guide the conversation. The goal isn't softer consequences. It's consequences that actually teach.

Kids with ADHD benefit most when parents provide support at the exact moment behavior happens, a science-backed approach called "point of performance." Abruptly shifting from high-stimulation screen time to demanding tasks creates a "dopamine cliff," a brain chemistry drop that often shows up as resistance and conflict. Understanding both concepts helps parents smooth those transitions and build real skills and confidence in their kids over time.

A new Louis Theroux documentary on Netflix exposes the growing network of online influencers pushing sexism, misogyny, and a narrow vision of masculinity on boys and young men. Combined with last year's hit series Adolescence, it is a wake-up call for parents. The good news: there is a lot we can do. This week, I round up our most relevant blogs and podcast episodes from recent months, covering everything from the "interrupter" technique to boys' mental health, phones in schools, online sports betting, pornography, and the manosphere's exploitation of boys' loneliness. The research is clear that parents who show up with curiosity, honesty, and consistency have more influence than they realize.
