In the [[psychology]] of [[motivation]], '''balance theory''' is a theory of [[attitude change]], proposed by [[Fritz Heider]].<ref>Heider, Fritz (1958). ''The Psychology of Interpersonal Relations''. John Wiley & Sons.</ref> It conceptualizes the [[cognitive consistency]] motive as a drive toward psychological balance. The consistency motive is the urge to maintain one's values and beliefs over time. Heider proposed that "sentiment" or liking relationships are balanced if the [[affect (psychology)|affect]] [[valence (psychology)|valence]] in a system multiplies out to a positive result.

在动机心理学中，平衡理论是弗里茨 · 海德提出的态度变化理论。它将认知一致性动机概念化为一种心理平衡的驱动力。一致性的动机是随着时间的推移保持一个人的价值观和信仰的强烈愿望。海德提出，如果一个系统中的情感效价翻倍成一个积极的结果，那么“情感”或喜欢关系就是平衡的。

海德的 P-O-X 模型
For example: a Person (<math>P</math>) who likes (<math>+</math>) an Other (<math>O</math>) person will be balanced by the same valence attitude on behalf of the other. Symbolically, <math>P (+) > O</math> and <math>P < (+) O</math> results in psychological balance.

Cognitive balance is achieved when there are three positive links or two negatives with one positive. Two positive links and one negative like the example above creates imbalance or [[cognitive dissonance]].

不断增加的迹象表明，这个人会察觉到这种关系中的不平衡(负乘法产品) ，并且会有动力以某种方式纠正这种不平衡。这个人可以:

[[Frank Harary]] and Dorwin Cartwright looked at Heider's triads as 3-cycles in a [[signed graph]]. The sign of a [[path (graph theory)|path]] in a [[graph (discrete mathematics)|graph]] is the product of the signs of its edges. They considered [[cycle (graph theory)|cycle]]s in a signed graph representing a social network.

平衡理论对社会动力学的意义由 Anatol Rapoport 表达:
:The hypothesis implies roughly that attitudes of the group members will tend to change in such a way that one's [[friend of a friend|friends' friends]] will tend to become one's friends and one's enemies' enemies also one's friends, and one's enemies' friends and one's friends' enemies will tend to become one's enemies, and moreover, that these changes tend to operate even across several removes (one's friends' friends' enemies' enemies tend to become friends by an iterative process).<ref>[[Anatol Rapoport]] (1963) "Mathematical models of social interaction", in [https://archive.org/details/handbookofmathem017893mbp ''Handbook of Mathematical Psychology'', v. 2], pp 493 to 580, especially 541, editors: R.A. Galanter, R.R. Lace, E. Bush, [[John Wiley & Sons]]</ref>
The hypothesis implies roughly that attitudes of the group members will tend to change in such a way that one's friends' friends will tend to become one's friends and one's enemies' enemies also one's friends, and one's enemies' friends and one's friends' enemies will tend to become one's enemies, and moreover, that these changes tend to operate even across several removes (one's friends' friends' enemies' enemies tend to become friends by an iterative process).
这个假设大致意味着群体成员的态度会倾向于这样的改变: 一个人的朋友的朋友会变成一个人的朋友，一个人的敌人的敌人也会变成一个人的朋友，一个人的敌人的朋友和一个人的朋友的敌人也会变成一个人的敌人，而且，这些改变甚至会在几次移除中发生(一个人的朋友的朋友的敌人的敌人也会通过一个迭代过程变成朋友)。
Note that a triangle of three mutual enemies makes a clusterable graph but ''not'' a balanced one. Therefore, in a clusterable network one ''cannot'' conclude that [[the enemy of my enemy is my friend]], although this aphorism is a fact in a balanced network.

请注意，由三个共同的敌人组成的三角形形成的是一个可聚集的图，而不是一个平衡的图。因此，在一个可聚集的网络中，不能断定敌人的敌人就是我的朋友，尽管这句格言在一个平衡的网络中是一个事实。
===Criticism===
Claude Flament<ref>Claude Flament (1963) ''Application of Graph Theory to Group Structure'', translators Maurice Pinard, Raymond Breton, Fernand Fontaine, chapter 3: Balancing Processes, page 92, [[Prentice-Hall]]</ref> expressed a limit to balance theory imposed by reconciling [[weak ties]] with relationships of stronger force such as [[human bonding|family bonds]]:
Claude Flament expressed a limit to balance theory imposed by reconciling weak ties with relationships of stronger force such as family bonds:
克劳德 · 弗兰特通过调和弱关系与强关系(如家庭纽带)之间的关系，表达了对平衡理论的限制:
:One might think that a [[graph (abstract data type)|valued algebraic graph]] is necessary to represent psycho-social reality, if it is to take into account the degree of intensity of interpersonal relationships. But in fact it then seems hardly possible to define the balance of a graph, not for mathematical but for psychological reasons. If the relationship ''AB'' is +3, the relationship ''BC'' is –4, what should the ''AC'' relationship be in order that the triangle be balanced? The psychological hypotheses are wanting, or rather they are numerous and little justified.

如果要考虑人际关系的紧张程度，人们可能会认为有必要用一个有价值的代数图来表示心理社会现实。但事实上，定义一个图表的平衡似乎几乎是不可能的，不是出于数学上的原因，而是出于心理学上的原因。如果 AB 的关系是 + 3，BC 的关系是-4，那么 AC 的关系应该是什么，才能使三角形平衡？心理学上的假设是缺乏的，或者更确切地说，这些假设数量众多，而且没有多少合理性。
At the 1975 Dartmouth College colloquium on balance theory, Bo Anderson struck at the heart of the notion:<ref>Bo Anderson (1979) "Cognitive Balance Theory and Social Network Analysis: Remarks on some fundamental theoretical matters", pages 453 to 69 in ''Perspectives on Social Network Research'', see page 462.</ref>
At the 1975 Dartmouth College colloquium on balance theory, Bo Anderson struck at the heart of the notion:
在1975年达特茅斯学院关于平衡理论的座谈会上，Bo Anderson 触及了这个概念的核心:
:In graph theory there exists a ''formal'' balance theory that contains theorems that are ''analytically'' true. The statement that Heider's ''psychological'' balance can be represented, in its essential aspects, by a suitable interpretation of that ''formal balance theory'' should, however, be regarded as problematical. We cannot routinely identify the positive and negative lines in the formal theory with the positive and negative "sentiment relations", and identify the formal balance notion with the ''psychological'' idea of balance or structural tension. .. It is puzzling that the fine structure of the relationships between formal and psychological balance has been given scant attention by balance theorists.

在图论中，有一种形式的平衡理论，其中包含的定理在分析上是正确的。然而，关于海德尔的心理平衡可以通过对形式平衡理论的适当解释来体现其本质方面的说法，应该被视为是有问题的。我们不能将形式理论中的积极与消极的“情感关系”常规性地区分为积极与消极的“情感关系” ，也不能将形式平衡概念与心理学中的平衡或结构张力概念相区分。..形式平衡与心理平衡之间关系的精细结构一直没有得到平衡理论家的重视，这一点令人费解。

:No cycle has exactly one negative edge.
No cycle has exactly one negative edge.
没有一个循环恰好有一个负边。

平衡理论对社会动力学的意义由 Anatol Rapoport 表达:
:The hypothesis implies roughly that attitudes of the group members will tend to change in such a way that one's [[friend of a friend|friends' friends]] will tend to become one's friends and one's enemies' enemies also one's friends, and one's enemies' friends and one's friends' enemies will tend to become one's enemies, and moreover, that these changes tend to operate even across several removes (one's friends' friends' enemies' enemies tend to become friends by an iterative process).<ref>[[Anatol Rapoport]] (1963) "Mathematical models of social interaction", in [https://archive.org/details/handbookofmathem017893mbp ''Handbook of Mathematical Psychology'', v. 2], pp 493 to 580, especially 541, editors: R.A. Galanter, R.R. Lace, E. Bush, [[John Wiley & Sons]]</ref>

这个假设大致意味着群体成员的态度会倾向于这样的改变: 一个人的朋友的朋友会变成一个人的朋友，一个人的敌人的敌人也会变成一个人的朋友，一个人的敌人的朋友和一个人的朋友的敌人也会变成一个人的敌人，而且，这些改变甚至会在几次移除中发生(一个人的朋友的朋友的敌人的敌人也会通过一个迭代过程变成朋友)。
Note that a triangle of three mutual enemies makes a clusterable graph but ''not'' a balanced one. Therefore, in a clusterable network one ''cannot'' conclude that [[the enemy of my enemy is my friend]], although this aphorism is a fact in a balanced network.

请注意，由三个共同的敌人组成的三角形形成的是一个可聚集的图，而不是一个平衡的图。因此，在一个可聚集的网络中，不能断定敌人的敌人就是我的朋友，尽管这句格言在一个平衡的网络中是一个事实。

Claude Flament<ref>Claude Flament (1963) ''Application of Graph Theory to Group Structure'', translators Maurice Pinard, Raymond Breton, Fernand Fontaine, chapter 3: Balancing Processes, page 92, [[Prentice-Hall]]</ref> expressed a limit to balance theory imposed by reconciling [[weak ties]] with relationships of stronger force such as [[human bonding|family bonds]]:
Claude Flament expressed a limit to balance theory imposed by reconciling weak ties with relationships of stronger force such as family bonds:
克劳德 · 弗兰特通过调和弱关系与强关系(如家庭纽带)之间的关系，表达了对平衡理论的限制:
:One might think that a [[graph (abstract data type)|valued algebraic graph]] is necessary to represent psycho-social reality, if it is to take into account the degree of intensity of interpersonal relationships. But in fact it then seems hardly possible to define the balance of a graph, not for mathematical but for psychological reasons. If the relationship ''AB'' is +3, the relationship ''BC'' is –4, what should the ''AC'' relationship be in order that the triangle be balanced? The psychological hypotheses are wanting, or rather they are numerous and little justified.

如果要考虑人际关系的紧张程度，人们可能会认为有必要用一个有价值的代数图来表示心理社会现实。但事实上，定义一个图表的平衡似乎几乎是不可能的，不是出于数学上的原因，而是出于心理学上的原因。如果 AB 的关系是 + 3，BC 的关系是-4，那么 AC 的关系应该是什么，才能使三角形平衡？心理学上的假设是缺乏的，或者更确切地说，这些假设数量众多，而且没有多少合理性。
At the 1975 Dartmouth College colloquium on balance theory, Bo Anderson struck at the heart of the notion:<ref>Bo Anderson (1979) "Cognitive Balance Theory and Social Network Analysis: Remarks on some fundamental theoretical matters", pages 453 to 69 in ''Perspectives on Social Network Research'', see page 462.</ref>
At the 1975 Dartmouth College colloquium on balance theory, Bo Anderson struck at the heart of the notion:
在1975年达特茅斯学院关于平衡理论的座谈会上，Bo Anderson 触及了这个概念的核心:
:In graph theory there exists a ''formal'' balance theory that contains theorems that are ''analytically'' true. The statement that Heider's ''psychological'' balance can be represented, in its essential aspects, by a suitable interpretation of that ''formal balance theory'' should, however, be regarded as problematical. We cannot routinely identify the positive and negative lines in the formal theory with the positive and negative "sentiment relations", and identify the formal balance notion with the ''psychological'' idea of balance or structural tension. .. It is puzzling that the fine structure of the relationships between formal and psychological balance has been given scant attention by balance theorists.

在图论中，有一种形式的平衡理论，其中包含的定理在分析上是正确的。然而，关于海德尔的心理平衡可以通过对形式平衡理论的适当解释来体现其本质方面的说法，应该被视为是有问题的。我们不能将形式理论中的积极与消极的“情感关系”常规性地区分为积极与消极的“情感关系” ，也不能将形式平衡概念与心理学中的平衡或结构张力概念相区分。..形式平衡与心理平衡之间关系的精细结构一直没有得到平衡理论家的重视，这一点令人费解。
