If you were on Twitter
Dear educator, if you were on Twitter yesterday, you might have found:
But you weren’t on Twitter yesterday, so it’s likely that you saw none of this. And, yes, you probably also would have seen someone posting a picture of some strawberries or talking about how they just went to their kid’s Little League game. Or some friendly banter between friends. Or even someone chatting about walking their dog or the great sandwich that they just ate. Good grief, who posts that stuff? Don’t they have anything better to do with their lives?
Instead of being on Twitter yesterday, perhaps you were talking with your neighbors over the back fence. That’s a real relationship, isn’t it? Not like those so-called online ‘friendships’ where people ‘like’ each other. That back fence relationship is great, isn’t it? Almost every day you share little tidbits with each other. Much of it is banal or just friendly chatter, but much of it also is useful: where’s the best place to get this, how can I find that, do you have any suggestions for how best to accomplish this other thing, by the way I saw this thing today that might interest you, and so on. At some point you also realized that those small day-to-day interactions over the back fence about each others’ strawberries and Little League games and dog walks and sandwiches have somehow added up to something more enduring: lasting friendships and a positive interdependency that you never would have anticipated at the beginning.
Because you’re not on Twitter, what you don’t realize is that Twitter is the back fence you share with your neighbors. Except your neighbors are people all over the world who share your interests and passions and can help you accomplish your personal and professional goals. Every day you have a chance to learn from these online neighbors. Every day you have a chance to receive resources that you otherwise never would have found. Every day you have a chance to intersect with people who care about what you care about and are willing to help you be more productive and save time. And much of it is banal or just friendly chatter, but much of it also is useful.
What’s that? You don’t want to be part of a community that shares your interests? You don’t have time to learn? You’d rather not receive helpful resources? Oh, okay. Good for you, I guess.
Why, again, dear educator, aren’t you on Twitter?

"Deepfakes" and "cheap fakes" are becoming strikingly convincing — even ones generated on freely available apps.
- A writer named Magdalene Visaggio recently used FaceApp and Airbrush to generate convincing portraits of early U.S. presidents.
- "Deepfake" technology has improved drastically in recent years, and some countries are already experiencing how it can weaponized for political purposes.
- It's currently unknown whether it'll be possible to develop technology that can quickly and accurately determine whether a given video is real or fake.
The future of deepfakes<p>In 2018, Gabon's president Ali Bongo had been out of the country for months receiving medical treatment. After Bongo hadn't been seen in public for months, rumors began swirling about his condition. Some suggested Bongo might even be dead. In response, Bongo's administration released a video that seemed to show the president addressing the nation.</p><p>But the <a href="https://www.facebook.com/watch/?v=324528215059254" target="_blank">video</a> is strange, appearing choppy and blurry in parts. After political opponents declared the video to be a deepfake, Gabon's military attempted an unsuccessful coup. What's striking about the story is that, to this day, experts in the field of deepfakes can't conclusively verify whether the video was real. </p><p>The uncertainty and confusion generated by deepfakes poses a "global problem," according to a <a href="https://www.brookings.edu/research/is-seeing-still-believing-the-deepfake-challenge-to-truth-in-politics/#cancel" target="_blank">2020 report from The Brookings Institution</a>. In 2018, the U.S. Department of Defense released some of the first tools able to successfully detect deepfake videos. The problem, however, is that deepfake technology keeps improving, meaning forensic approaches may forever be one step behind the most sophisticated forms of deepfakes. </p><p>As the 2020 report noted, even if the private sector or governments create technology to identify deepfakes, they will:</p><p style="margin-left: 20px;">"...operate more slowly than the generation of these fakes, allowing false representations to dominate the media landscape for days or even weeks. "A lie can go halfway around the world before the truth can get its shoes on," warns David Doermann, the director of the Artificial Intelligence Institute at the University of Buffalo. And if defensive methods yield results short of certainty, as many will, technology companies will be hesitant to label the likely misrepresentations as fakes."</p>
Context is everything.
The COVID-19 pandemic has introduced a number of new behaviours into daily routines, like physical distancing, mask-wearing and hand sanitizing. Meanwhile, many old behaviours such as attending events, eating out and seeing friends have been put on hold.
A new study looks at how images of coffee's origins affect the perception of its premiumness and quality.
- Images can affect how people perceive the quality of a product.
- In a new study, researchers show using virtual reality that images of farms positively influence the subjects' experience of coffee.
- The results provide insights on the psychology and power of marketing.
