Lorem ipsum dolor sit amet, consectetur adipiscing elit. Itaque a sapientia praecipitur se ipsam, si usus sit, sapiens ut relinquat. Expectoque quid ad id, quod quaerebam, respondeas. Diodorus, eius auditor, adiungit ad honestatem vacuitatem doloris. Nulla profecto est, quin suam vim retineat a primo ad extremum. Si longus, levis;

Possumusne ergo in vita summum bonum dicere, cum id ne in cena quidem posse videamur?

Addebat etiam se in legem Voconiam iuratum contra eam facere non audere, nisi aliter amicis videretur. Duo Reges: constructio interrete. Nullum inveniri verbum potest quod magis idem declaret Latine, quod Graece, quam declarat voluptas. Causa autem fuit huc veniendi ut quosdam hinc libros promerem. Cetera illa adhibebat, quibus demptis negat se Epicurus intellegere quid sit bonum. Nihil enim iam habes, quod ad corpus referas; Hoc loco tenere se Triarius non potuit. Quae cum magnifice primo dici viderentur, considerata minus probabantur.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Parvi enim primo ortu sic iacent, tamquam omnino sine animo sint. Quod si ita se habeat, non possit beatam praestare vitam sapientia. Qualis ista philosophia est, quae non interitum afferat pravitatis, sed sit contenta mediocritate vitiorum? Nummus in Croesi divitiis obscuratur, pars est tamen divitiarum. Duo Reges: constructio interrete. An, partus ancillae sitne in fructu habendus, disseretur inter principes civitatis, P.

Quid ergo attinet dicere: Nihil haberem, quod reprehenderem, si finitas cupiditates haberent? De ingenio eius in his disputationibus, non de moribus quaeritur. Istam voluptatem, inquit, Epicurus ignorat? Vos autem cum perspicuis dubia debeatis illustrare, dubiis perspicua conamini tollere. Non enim in selectione virtus ponenda erat, ut id ipsum, quod erat bonorum ultimum, aliud aliquid adquireret. Quae similitudo in genere etiam humano apparet. Quid ergo attinet gloriose loqui, nisi constanter loquare? Et ais, si una littera commota sit, fore tota ut labet disciplina.

An tu me de L. Hunc vos beatum; An est aliquid, quod te sua sponte delectet? At ille pellit, qui permulcet sensum voluptate. Quis Pullum Numitorium Fregellanum, proditorem, quamquam rei publicae nostrae profuit, non odit?

Limitations

Your BATNA's strength can easily be affected by unexpected changes in conditions. At the same time, determining BATNAs for you and your counterparty is difficult due to subjectivity, as we have a tendency to overestimate the strength of our BATNA and to underestimate the strength of the other side's BATNA. 

Other factors influencing BATNA, like relationship value and the likelihood of the other party maintaining their side of the bargain are also difficult to value and measure in a quantifiable manner.

Finally, using BATNA as a mental model to assist in negotiations should not be counterposed to developing rapport, active listening and other methods to connect and find potential win-win options. 

In Practice

The Brexit BATNA. 

In August 2018 British Prime Minister Theresa May revealed a plan of contingency for exiting the European Union (E.U.) if the so-called Brexit negotiations ended in an impasse, revealing the Government’s BATNA to quell the public’s fears.

Salary negotiation.

In a salary negotiation, the employee might have a basic BATNA of their current salary, assuming that the negotiation will not end with them losing their job. They might increase this by applying for an alternative position with a higher salary, which will become their new BATNA. In such a case, it is not a like for like comparison so the BATNA might become difficult to assess. For the company, they must consider the cost of losing the staff member if they do not meet their expectations. Again this cost is hard to measure.

BATNA is a fundamental mental model in negotiation theory. 

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

Connected models: 

  • WATNA: the worst alternative to a negotiated agreement is the other side of this equation. 
  • Opportunity cost: BATNA is essentially the same as opportunity cost, applied to the specific purpose of negotiations. 

Complementary models: 

  • Porter's five forces: particularly as it relates to the bargaining power of suppliers. 
  • Non-violent communication: challenges this model in attempting to find a win-win alternative. 
  • Cialidini’s six principles of persuasion: a powerful option used in conjunction with any negotiation process. 
  • Mutually assured destruction: where the BATNAs result in disaster for both parties, negotiation becomes an imperative. 
  • Cost-benefit analysis: in considering BATNA.
  • Sunk cost fallacy: to support walking away from a protracted, even expensive negotiation. 
Origins & Resources

BATNA was created by negotiation researchers Roger Fisher and William Ury of the Harvard Program on Negotiation and presented in their fundamental 1981 book Getting to Yes: Negotiating Without Giving In.
