Present Your Ideas: Overcome the "Curse of Knowledge"
Successful presenters understand that it’s not about them; it’s about their audience, so says Chris Anderson, the curator of TED Talks.
Chris Anderson is the curator of TED (Technology, Entertainment, Design), which hosts conferences in North America and Europe each year and an open-access website where TED talks can be viewed by the public.
Chris Anderson: How do you make good presentations? I think it's astonishingly hard actually to do it because everyone suffers from something that <a href="http://bigthink.com/experts/stevenpinker" target="_blank">Steven Pinker</a> calls the “curse of knowledge.” When you know something, you actually can't remember what it's like not to know it. I mean, you just can't. So when you explain it to someone, nine times out of ten you start from a place where they aren't and they don't really understand what you're saying. And that is the reason why so many talks and presentations fail.
Take your audience on a journey
So if you think about it, what's happening during a great talk, it's a real miracle. You are transferring an idea from your mind to those listening. An idea is this incredibly complex neurological thing. I mean, if you could actually map it it would probably be billions, literally billions of neurons go to make this pattern. How on earth do you get a pattern that involves billions of neurons to transfer to another mind?
The only way you can do it is step-by-step. So that is the key metaphor for me is you think of a talk or a presentation as a journey. You start where your audience is and you give them a reason to want to come with you on this journey. So make them curious, make them care about a problem, make them care about you somehow. And then take them step by step with each little contribution to the idea adding up a little bit so that they don't get lost in jargon or wonder where on earth you're going. Those are the keys to it. To actually execute on that is hard, but thinking of it as a journey helps.
Successful presenters understand that it’s not about them; it’s about their audience, so says Chris Anderson, the curator of TED Talks, a wildly popular global set of conferences whose viewership surpassed 1 billion in 2012. The key is to analyze your audience by mapping out their reality and what they might want to know. From that point forward, it’s all about emotional connection. In this lesson, Anderson teaches you simple tips for making your presentations more compelling and persuasive. Learn more at Big Think Edge.
Duke University researchers might have solved a half-century old problem.
- The blend of three polymers provides enough flexibility and durability to mimic the knee.
- The next step is to test this hydrogel in sheep; human use can take at least three years.

Their <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/adfm.202003451" target="_blank">new paper</a>, published in the journal,<em> Advanced Functional Materials</em>, details this exciting evolution of this frustrating joint.<br></p><p>Researchers have sought materials strong and versatile enough to repair a knee since at least the seventies. This new hydrogel, comprised of three polymers, might be it. When two of the polymers are stretched, a third keeps the entire structure intact. When pulled 100,000 times, the cartilage held up as well as materials used in bone implants. The team also rubbed the hydrogel against natural cartilage a million times and found it to be as wear-resistant as the real thing. </p><p>The hydrogel has the appearance of Jell-O and is comprised of 60 percent water. Co-author, Feichen Yang, <a href="https://today.duke.edu/2020/06/lab-first-cartilage-mimicking-gel-strong-enough-knees" target="_blank">says</a> this network of polymers is particularly durable: "Only this combination of all three components is both flexible and stiff and therefore strong." </p><p> As with any new material, a lot of testing must be conducted. They don't foresee this hydrogel being implanted into human bodies for at least three years. The next step is to test it out in sheep. </p><p>Still, this is an exciting step forward in the rehabilitation of one of our trickiest joints. Given the potential reward, the wait is worth it. </p><p><span></span>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

What would it be like to experience the 4th dimension?
- 10-15% of people visiting emergency rooms eventually develop symptoms of long-lasting PTSD.
- Early treatment is available but there's been no way to tell who needs it.
- Using clinical data already being collected, machine learning can identify who's at risk.
