 Finally, psychologists themselves have increasingly focused on characterizing the cognitive profile of understanding. Thus Tania Lombrozo and colleagues have explored the question of why we seek understanding, and how activities such as offering explanations aid in the acquisition and retention of understanding (Lombrozo, 2012; Williams &amp; Lombrozo, 2010, 2013; Lombrozo &amp; Wilkenfeld 2019). Psychologists have also explored the empirical question of how good (or bad) we are at identifying real relationships and dependencies in the world. According to Frank Keil, for example, we are not good at this at all, and we frequently fall prey to illusions of understanding (Keil 2006; cf. Ylikoski 2009). For instance, we often think we understand how a helicopter achieves lift, or how moving the pedals on a bicycle help to propel the bike forward.  But in both cases, we are often well wide of the mark (Keil 2006; cf. Grimm 2009; Sloman &amp; Fernbach 2017).
