The core information is not altered. The science is intact. But if I’m going to be an effective communicator, I’m going to shape the content in a way that can best be received by the receptors of that audience.
That’s the only way you know you’re communicating. Otherwise you’re just giving a lecture, you’re facing the board and talking to the board, and people in the classroom behind you have to meet you at the board. The educator who says ‘Oh, these people just don’t have an interest in learning’ should just be fired on the spot.
A real educator will try to understand what the receptors look like in every individual, in every person they’re tasked with teaching. For many people there are some common receptors so you can get halfway there. But if you want to get all the way there, that means [understanding] what are the receptors in a 12-year-old versus a 20-year-old versus a 50- or 80-year old. If the person grew up in a city versus the suburbs or in the countryside, if they’re foreign, if they grew up wealthy, struggling—all of this will feed the demographics of your audience.
If you don’t care [about the demographic], then you’re not in a position to complain that not everyone understood your message.
