So do they have, you know, interesting perspective, feedback on it from their perspective of being right in this range?
1:56
Yeah, it's funny.
1:56
So I, just a little context, I'm a university professor.
2:00
I, I, or a professional nerd, as I tell my kids.
2:03
Uh, I, um, I teach a large 150-person class called Using Behavioral Science to Change the World, and it's all about using, you know, psychology, social psychology, et cetera, to solve problems.
2:15
And one of the problems we focus on is stress and wellbeing, so we just did that today [laughs] actually.
2:20
And, uh, what's funny is, you know, the book's called 10 to 25 because that's everything between the onset of puberty, which is around 10, to 25, which is when people tend to take on an adult-like role.
6:03
You say it's not a flaw, it's a feature.
12:10
back in probably the late eighties, early nineties.
12:12
Okay.
12:13
So I, we won't say where I was at that time, but I was trying to kiss Nikki out by the swing set.
12:19
Yeah.
12:21
It was more like the play shed.
12:23
She wasn't into the swing set.
12:25
But yeah, I mean that technology now with the amount of fixation that we have, the amount of ability to correct the versatility is amazing.
14:50
got to determine if they're a healthy form of footwear.
9:43
So David, mindful of these core needs of adolescents and knowing that you were once a teacher, how do you find teachers responding to your book and the things that you hope that they might learn or do, and are there things that you're doing to work with educators across this country and beyond?
10:04
I love teachers.
10:04
I love working with them.
10:05
It's...
10:06
They're the group I think about first, often.
10:08
Teachers are constantly under threat.
10:10
I mean, like, everyone's blaming teachers all the time for everything.
12:40
Has it changed the way you interact with your own kids, the, the ways you interact with colleagues or, or just move through the world?
8:09
Yeah.
8:09
So in this, this Jeff Cohen gets the credit for coming up with this, but there are a lot of other collaborators like Valerie Purdy Greenaway and Alison Master and others who are involved.
8:18
But basically.
8:19
It's a type of mindset moment, you could call it.
8:22
And it's the critical feedback interaction that you do your work in earnest, whether you're an employee or a student or even a professor, and you submit it for review by an expert.
8:35
And in a perfect world, that expert points out the things that were not yet up to standard.
8:41
And then you're like, oh, thanks.

11 MINS LATER

19:46
Could you explain to someone who has not heard that, that term before? What is the mentor mindset?
12:48
This is a really key thing, I think, for us to understand as, as managers, as leaders, as parents.
12:53
Yeah.
12:53
I mean, I think...
12:54
Look, there's been a lot written about psychological safety, and you can see it all over the Harvard Business Review, et cetera, and it's not wrong.
13:01
But I think that the, the simple idea is that if, if you want employees or children or students or players in a s- sports team to go out and do awesome stuff, stuff that's impressive, that's above and beyond, et cetera, they need to feel safe from the perspective of they're not gonna be judged, blamed, shamed, punished if things go wrong.
13:25
Because basically, if you take a risk and then you'll be punished for that risk, then people are less likely to do it.
13:31
Okay, so that part of psychological safety, that's all legitimate.

15 MINS LATER

28:52
Hmm.
11:29
Well,
11:30
I mean, there's a, we, we, I, we have four kids, so we're, you know, plenty of mistakes happening in my house.
11:36
My wife has not read my book.
11:38
She was like, you should read Dr. Becky's book.
11:40
That was her take.
11:42
She's like, or I should write the book.
11:43
I don't know.

31 MINS LATER

43:04
Can you explain to viewers what Fuse is and a little bit about how you are actually implementing this now?
10:15
ads.
10:16
And tobacco is wacko if you're a teen is super lame.
10:19
Right.
10:20
Can you imagine being after school, sitting in a circle with someone you have a crush on? You're finally like close to her.
10:27
Your arms almost touch and she offers you a cigarette and you're like, sorry, because I'm a teen, that's wacko.
10:35
Like the 0% of teenagers would respond that way.
10:38
So the Truth Campaign was in response to these kind of terrible conventional public health approaches that get adolescent psychology wrong.

22 MINS LATER

32:57
What problem were you trying to solve there?
7:39
What else is it trying to do? What's its mission?
7:42
Of course, the brain develops, and so there are different levels of ability and maturity, but what we tend to focus on is in the ten to twenty-five range, and even maybe a little earlier, there's a shift in motivational priorities.
7:54
And those motivational priorities can influence what young people choose to pay attention to.
8:00
That is, where do they deploy their considerable intellectual powers? And once you think of it as a motivation problem and not solely an ability problem, then you realize, well, maybe I'm not tapping into the right source of motivation.
8:15
And it's like our conventional view is that kids are motivated primarily by the desire to please their parents, or at least not piss off their parents.
8:23
And we get offended.
8:24
We're like, "Don't you know how angry you're making me, like right now?" And that feels like they're trying to intentionally get our goat for something.
10:19
[laughs]
