addressing biases

Nick Phillips:

Intellectual diversity addresses a fundamental problem in human cognition: we seek out information that confirms the views we already have. As Jonathan Haidt has argued, this instinct is well-adapted to creating intra-group solidarity, which is useful when competing for power with other groups. But if the goal is to seek the truth, it’s poison. If everyone in your group shares the same biases, that group will block new information that doesn’t conform to those biases. Since no one is right 100 percent of the time, this dynamic guarantees that falsehoods will persist. 

One solution is to attempt to purge individuals of their biases. But cognitive psychologists don’t yet understand how to do this. The only method that reliably solves the confirmation bias problem is to create groups made up of individuals with different biases. In such an environment, countervailing biases checks one another, prodding at weak points and raising questions a colleague didn’t think to ask. This dynamic is highly adapted to truth-seeking, because it forces every person to justify their biases on grounds other than tribalism.

studies prove

Kevin Williamson:

Studies have a way of ceasing to be studies once they are taken up by politicians-in-print like Ezra Klein. They become dueling implements. Mary Branham of the Council of State Governments: “Evidence Shows Raising Minimum Wage Hasn’t Cost Jobs” vs. Max Ehrenfreund of the Washington Post: “‘Very Credible’ New Study on Seattle’s $15 Minimum Wage Has Bad News for Liberals” vs. Arindrajit Dube of the New York Times: “Minimum Wage and Job Loss: One Alarming Seattle Study Is Not the Last Word.” Much of this is predictable partisan pabulum. The study that confirms my priors is science. The study that challenges my preferences is … just one study. Our friends among the global-warming alarmists, embarrassed by the fact that every time Al Gore shows up to give a speech it turns out to be the coldest March day in 30 years, are forever lecturing us that weather doesn’t tell us anything useful about climate — except when it’s hot in the summer, or there’s a drought in California, or there’s a hurricane in Florida.

I am a registered “global-warming alarmist,” but Williamson is absolutely right about all this.
