Despite the iPad's popularity—Apple has sold nearly 15 million of them and just came out with the iPad2; and there are dozens of competitors, like the Samsung Galaxy—early studies indicate that these finger-based tablets are passive devices that have limited use in higher education. They are great for viewing media and allow students to share readings. But professors cannot use them to mark up material on the fly and show changes to students in response to their questions, a type of interactivity that has been a major thrust in pedagogy.

Google also tries to point out predictable traps in performance reviews, which are often done with input from a group. The company has compiled a list of “cognitive biases” for employees to keep handy during these discussions. For example, somebody may have just had a bad experience with the person being reviewed, and that one experience inevitably trumps recollections of all the good work that person has done in recent months. There’s also the “halo/horns” effect, in which a single personality trait skews someone’s perception of a colleague’s performance.
