Educators and administrators must build new supports for faculty and student success in a world where the classroom might become virtual in the blink of an eye.
- If you or someone you know is attending school remotely, you are more than likely learning through emergency remote instruction, which is not the same as online learning, write Rich DeMillo and Steve Harmon.
- Education institutions must properly define and understand the difference between a course that is designed from inception to be taught in an online format and a course that has been rapidly converted to be offered to remote students.
- In a future involving more online instruction than any of us ever imagined, it will be crucial to meticulously design factors like learner navigation, interactive recordings, feedback loops, exams and office hours in order to maximize learning potential within the virtual environment.

Master negotiator Chris Voss breaks down how to get what you want during negotiations.
- Former FBI negotiator Chris Voss explains how forced empathy is a powerful negotiating tactic.
- The key is starting a sentence with "What" or "How," causing the other person to look at the situation through your eyes.
- What appears to signal weakness is turned into a strength when using this tactic.
3 Tips on Negotiations, with FBI Negotiator Chris Voss | Best of '16 | Big Think<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="b86d518e9f0c9f9d7a7c686e07798152"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/-FLlBchonwM?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>This question forces a response, but—and this is key—the other person has to consider your side of the argument. They have to look at the situation from your perspective if they hope to offer a solution.</p><p>Offering a real-world example, Voss mentions coaching a high-end real estate agent. They were leasing an expensive home in the Hollywood Hills. The first time the negotiators asked the "how" question, the leasing agent relented on a number of terms. A little while later, they asked again. This time, the agent said, "If you want the house you're going to have to do it," signaling that the end of negotiations had been reached. </p><p>Voss says that "how" is not the only word that works. "What" is also a powerful entry into negotiations, such as "What am I supposed to do?" Again, you're forcing the other person to empathize. </p><p>This is a particularly tricky skill during a time when most conversations are online. Nuance is impossible without the immediacy of pantomimes and vocal fluctuations. Whataboutism is too easy an escape. </p>

In his book, "Against Empathy," Yale psychology professor Paul Bloom writes that effective altruists are able to focus on what really matters in everyday life.</p><p>For example, he compares politics to sports. Rooting for your favorite team isn't based in rationality. If you're a Red Sox fan, Yankees stats don't matter. You just want to destroy them. This, he believes, is how most people treat politics. "They don't care about truth because, for them, it's not really about truth."</p><p>Bloom writes that if his son believed our ancestors rode dinosaurs, it would horrify him, but "I can't think of a view that matters less for everyday life." We have to strive for rationality when the stakes are high. When involved in real decision-making processes that will affect their life, people are better able to express ideas and make arguments, and are more receptive to opposing ideas. </p><p>Because we "become inured to problems that seem unrelenting," it's imperative to make the problem seem immediate. As Voss says, giving the other side "the illusion of control" is one way of accomplishing this, as it forces them to take action. When people feel out of control, negotiations are impossible. People dig their heels in and refuse to budge. </p><p>What seems to be weakness is actually a strength. To borrow another martial arts metaphor, negotiations are like aikido: using your opponent's force against them while also protecting them from injury. Forcing empathy is one way to accomplish this task. You may get more than you ask for without the other side ever realizing they surrendered anything.</p><p>--</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>.
