Femoral-tibial angle "genu valgum" or "genu varum", the femoral-tibial angle is about 175 degrees. Femoral-tibial angle The femoral-tibial angle is the angle between the femur and tibia. In humans, the two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. In human females the femora converge more than in males because the pelvic bone is wider in females. In the condition "genu valgum" (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme
Less-is-better effect Less-is-better effect The less-is-better effect is a type of preference reversal that occurs when the lesser or smaller alternative of a proposition is preferred when evaluated separately, but not evaluated together. The term was first proposed by Christopher Hsee. In a 1998 study, Hsee, a professor at the Graduate School of Business of The University of Chicago, discovered a less-is-better effect in three contexts: "(1) a person giving a $45 scarf (from scarves ranging from $5-$50) as a gift was perceived to be more generous than one giving a $55 coat (from coats ranging from $50-$500); (2) an overfilled ice
