Questions About The Existence of Loss Aversion
Recently, studies have questioned the existence of loss aversion. In several studies examining the effect of losses in decision making under risk and uncertainty no loss aversion was found. There are several explanations for these findings: one, is that loss aversion does not exist in small payoff magnitudes; the other, is that the generality of the loss aversion pattern is lower than that thought previously. Finally, losses may have an effect on attention but not on the weighting of outcomes; as suggested, for instance, by the fact that losses lead to more autonomic arousal than gains even in the absence of loss aversion.
Loss aversion may be more salient when people compete. Gill and Prowse (2012) provide experimental evidence that people are loss averse around reference points given by their expectations in a competitive environment with real effort.
Loss aversion and the endowment effect are often confused. Gal (2006) argued that the endowment effect, previously attributed to loss aversion, is more parsimoniously explained by inertia than by a loss/gain asymmetry.

Famous quotes containing the words questions, existence, loss and/or aversion:
“An answer in words is delusive; it is really no answer to the questions you ask.”
—Ralph Waldo Emerson (1803–1882)
“No being exists or can exist which is not related to space in some way. God is everywhere, created minds are somewhere, and body is in the space that it occupies; and whatever is neither everywhere nor anywhere does not exist. And hence it follows that space is an effect arising from the first existence of being, because when any being is postulated, space is postulated.”
—Isaac Newton (1642–1727)
“War is bestowed like electroshock on the depressive nation; thousands of volts jolting the system, an artificial galvanizing, one effect of which is loss of memory. War comes at the end of the twentieth century as absolute failure of imagination, scientific and political. That a war can be represented as helping a people to “feel good” about themselves, their country, is a measure of that failure.”
—Adrienne Rich (b. 1929)
“Quintilian [educational writer in Rome around A.D. 100] thought that the earliest years of the child’s life were crucial. Education should start earlier than age seven, within the family. It should not be so hard as to give the child an aversion to learning. Rather, these early lessons would take the form of play—that embryonic notion of kindergarten.”
—C. John Sommerville (20th century)
