Overview

No, it's not just you — we all tend to overestimate the value of our possessions, and there's a name for it. 

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Paupertas si malum est, mendicus beatus esse nemo potest, quamvis sit sapiens. Quod quidem iam fit etiam in Academia. Id Sextilius factum negabat. Ita ceterorum sententiis semotis relinquitur non mihi cum Torquato, sed virtuti cum voluptate certatio. Multa sunt dicta ab antiquis de contemnendis ac despiciendis rebus humanis;

Illis videtur, qui illud non dubitant bonum dicere -; Quis Pullum Numitorium Fregellanum, proditorem, quamquam rei publicae nostrae profuit, non odit? Duo Reges: constructio interrete. Quod mihi quidem visus est, cum sciret, velle tamen confitentem audire Torquatum. Vitiosum est enim in dividendo partem in genere numerare. Sine ea igitur iucunde negat posse se vivere?

Et non ex maxima parte de tota iudicabis? Ad quorum et cognitionem et usum iam corroborati natura ipsa praeeunte deducimur. Sed in rebus apertissimis nimium longi sumus. Sin tantum modo ad indicia veteris memoriae cognoscenda, curiosorum. Beatum, inquit. Idemne potest esse dies saepius, qui semel fuit? Quid enim de amicitia statueris utilitatis causa expetenda vides. Nec vero alia sunt quaerenda contra Carneadeam illam sententiam. Quo plebiscito decreta a senatu est consuli quaestio Cn. Sed tamen omne, quod de re bona dilucide dicitur, mihi praeclare dici videtur.

Actionable Takeaways
  • Be mindful of the endowment heuristic in sales conversations. 

When purchasing something, be aware ...

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam, ut sint illa vendibiliora, haec uberiora certe sunt. Nos vero, inquit ille; Itaque eos id agere, ut a se dolores, morbos, debilitates repellant. Bork Duo Reges: constructio interrete.

Ita multa dicunt, quae vix intellegam. Quae quidem vel cum periculo est quaerenda vobis; Sed virtutem ipsam inchoavit, nihil amplius. Sic enim censent, oportunitatis esse beate vivere. Respondent extrema primis, media utrisque, omnia omnibus. Nam Pyrrho, Aristo, Erillus iam diu abiecti. Non minor, inquit, voluptas percipitur ex vilissimis rebus quam ex pretiosissimis. Igitur ne dolorem quidem. De malis autem et bonis ab iis animalibus, quae nondum depravata sint, ait optime iudicari. Si qua in iis corrigere voluit, deteriora fecit.

De malis autem et bonis ab iis animalibus, quae nondum depravata sint, ait optime iudicari. Servari enim iustitia nisi a forti viro, nisi a sapiente non potest. Bona autem corporis huic sunt, quod posterius posui, similiora. Sin aliud quid voles, postea. An me, inquam, nisi te audire vellem, censes haec dicturum fuisse? Ergo instituto veterum, quo etiam Stoici utuntur, hinc capiamus exordium. Tecum optime, deinde etiam cum mediocri amico. Sed emolumenta communia esse dicuntur, recte autem facta et peccata non habentur communia. Et adhuc quidem ita nobis progresso ratio est, ut ea duceretur omnis a prima commendatione naturae. Immo vero, inquit, ad beatissime vivendum parum est, ad beate vero satis.

Limitations

There have been critics of the Endowment Heuristic, with some claiming it does not exist or at least is not as apparent in real life as in fixed experiments. For example, some argue that the results from the mug experiment (see the ‘In Practice’ section) was more due to artificial scarcity. 

In Practice

Mugs.

This 1991 paper by Daniel Kahneman, Jack Knetcsch and Richard Thaler describes the classic example of the endowment heuristic involving mugs. In it, participants were given a mug and then given the chance to trade it. They found that the value attributed to owned mugs was twice as high as they were actually willing to pay for such a mug that they did not own.

The endowment heuristic is part of behavioural economics, stemming from the fast and slow thinking mental model and relating closely to loss aversion. 

Use the following examples of connected and complementary models to weave availability heuristic into your broader latticework of mental models. Alternatively, discover your own connections by exploring the category list above. 

Connected models: 

  • Fast and slow thinking: providing broader context to the endowment effect. 
  • Loss aversion and opportunity cost: a closely linked heuristic and bias. 
  • Lock in effect: and challenge of customer loyalty. 

Complementary models: 

  • Design thinking: consider strategies to co-design and increase ownership of initiatives. 
  • Lean startup: iterating with minimum viable products, allowing audience groups to access and own quickly and cheaply. 
Origins & Resources

Aristotle noted the tendency towards the Endowment Effect in Ancient Greece, when he explained: “For most things are differently valued by those who have them and by those who wish to get them: what belongs to us, and what we give away, always seems very precious to us.”

However, the term itself was first coined by the behavioural economist Richard Thaler in his 1980 paper entitled Toward a Positive Theory of Consumer Choice.’
