Surrogation

Surrogation is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Surrogation rather than just read about it. In short: Surrogation is a psychological phenomenon found in business practices whereby a measure of a construct of interest evolves to replace that construct. Research on performance measurement in management accounting identifies surrogation with "the tendency for managers to lose sight of the strategic construct(s) the measures are intended to represent, and subsequently act as though the measures are the constructs".

Key takeaways

Surrogation belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Surrogation to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Surrogation from memory before moving on to harder problems.

Reference excerpt

Surrogation is a psychological phenomenon found in business practices whereby a measure of a construct of interest evolves to replace that construct. Research on performance measurement in management accounting identifies surrogation with "the tendency for managers to lose sight of the strategic construct(s) the measures are intended to represent, and subsequently act as though the measures are the constructs". An everyday example of surrogation is a manager tasked with increasing customer satisfaction who begins to believe that the customer satisfaction survey score actually is customer satisfaction.

First usage Inspired by work by Yuji Ijiri, the term surrogation was coined by Willie Choi, Gary Hecht, and Bill Tayler in their paper, "Lost in Translation: The Effects of Incentive Compensation on Strategy Surrogation". They show managers tend to use measures as surrogates for strategy, acting as if measures were in fact the strategy when making optimization decisions. This appears to occur even if a measure-maximizing choice ultimately works against the strategy. They also show surrogation is exacerbated by incentive compensation. But, the phenomenon is distinct from wealth-maximizing behavior, since it persists both when incentives are removed and when they are changed to create an opportunity cost for maximizing the surrogate. The additional tendency to surrogate in the presence of incentives is reduced when managers are compensated based on multiple measures of a strategy rather than on a single measure. Choi, Hecht, and Tayler proposed attribute substitution as a mechanism for surrogation. Attribute substitution in decision-making involves a complex target attribute being replaced by a more easily accessible heuristic attribute. For this to occur, the target attribute must be relatively inaccessible, the heuristic attribute must be readily accessible, and the mental substitution must not be consciously rejected by the person. In the case of surrogation, the two attributes are related in that some party intends the heuristic attribute to serve as proxy for the target attribute.

Worked examples

Example 1 — a first encounter with Surrogation

Start with the simplest possible case. Write down what Surrogation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Surrogation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Surrogation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Surrogation

In research: Surrogation appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Surrogation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Surrogation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cognitive biases, Decision theory, so understanding it makes those chapters shorter.
In everyday life: Look for Surrogation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Surrogation in simple terms?

Why does Surrogation matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Surrogation?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
