- The Utter Uselessness of Job Interviews from the NY Times (2017) -- trashes the predictability of interviews generally, but touts the power of structured over unstructured interviews
- Google's Secret to Hiring the Best People from Wired (2015) -- similar to the article Rob sent out, cautions against the problem of confirmation bias in interviews. Advocates the use of a consistent, concise hiring rubric based on specific criteria. These criteria were determined in a meta-analysis of 85 years of data. The #1 predictor of job success is performance on a work sample (our demo lesson?). Tied for #2 were performance on cognitive tests (maybe educational background is our proxy?) and in a structured interview. The key is that the structured interview has a much greater predictive ability than an unstructured interview: "Structured interviews are predictive even for jobs that are themselves unstructured. We’ve also found that they cause both candidates and interviewers to have a better experience and are perceived to be most fair. So why don’t more companies use them? Well, they are hard to develop: You have to write them, test them, and make sure interviewers stick to them. And then you have to continuously refresh them so candidates don’t compare notes and come prepared with all the answers. It’s a lot of work, but the alternative is to waste everyone’s time with a typical interview that is either highly subjective, or discriminatory, or both."
- Don’t Blink! The Hazards of Confidence by Daniel Kahneman in the NY Times (2011) -- on how many of the things we are convinced we can predict end up being no more predictable than the roll of a dice. He does end on a hopeful note, however: "True intuitive expertise is learned from prolonged experience with good feedback on mistakes."

The Utter Uselessness of Job Interviews

History Class and the Fictions About Race in America

If nothing else, the incident may serve as yet another example of why social studies—and history in particular—is such a tricky subject to teach, at least via textbooks and multiple-choice tests. Its topics are inherently subjective, impossible to distill into paragraphs jammed with facts and figures alone. As the historian and sociologist Jim Loewen recently told me, in history class students typically “have to memorize what we might call ‘twigs.’ We’re not teaching the forest—we’re not even teaching the trees,” said Loewen, best known for his 1995 book Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong. “We are teaching twig history.”
This is in part why a growing number of educators are calling for a fundamental shift in how the subject is taught. Some are even calling on their colleagues to abandon traditional models of teaching history altogether. Instead of promoting the rote memorization of information outlined in a single, mass-produced textbook, these critics argue that teachers should use a variety of primary-source materials and other writings, encouraging kids to analyze how these narratives are written and recognize the ways in which inherent biases shape conventional instructional materials. In an essay for The Atlantic earlier this year, Michael Conway argued that history classes should focus on teaching children “historiography”—the methodologies employed by historians and the exploration of history itself as an academic discipline:
Currently, most students learn history as a set narrative—a process that reinforces the mistaken idea that the past can be synthesized into a single, standardized chronicle of several hundred pages. This teaching pretends that there is a uniform collective story, which is akin to saying everyone remembers events the same. Yet, history is anything but agreeable. It is not a collection of facts deemed to be “official” by scholars on high. It is a collection of historians exchanging different, often conflicting analyses. And rather than vainly seeking to transcend the inevitable clash of memories, American students would be better served by descending into the bog of conflict and learning the many "histories" that compose the American national story.
