By Linda Fisher Thornton We all need to know how to tell what's real news and what's not. While a headline may be compelling, we can easily damage our personal reputation and brand if we share it and it turns out to be "fake news." It's our job to "check stories out" to be sure that what we share is real. Our "Human Software" is Buggy While it's important for us to tell the difference between the real and the fake, our "human software" comes with bugs. One type of bug we all have is cognitive biases, and one of our biases causes us to readily believe headlines we already agree with (confirmation bias).
