Anchoring Bias
The tendency to rely disproportionately on the first piece of information encountered when making judgments or decisions. In Bible study, the first interpretation of a passage one hears — often in childhood or early faith formation — can function as an anchor that shapes all subsequent reading.

Anchoring bias is the cognitive tendency to give disproportionate weight to the first piece of information encountered on a topic — the 'anchor' — even when subsequent evidence should revise one's judgment significantly. Once an anchor is set, all further information is processed relative to it rather than on its own merits.
First documented by Amos Tversky and Daniel Kahneman in 1974 as part of their foundational work on heuristics and biases, anchoring has been demonstrated across contexts ranging from legal sentencing to medical diagnosis to price negotiation. The effect persists even when people know the anchor is arbitrary — we simply cannot fully escape the gravitational pull of the first number, story, or interpretation we encounter.
In the context of biblical interpretation, the anchoring bias is especially powerful because most readers first encounter the Bible through a specific tradition: a particular church, Sunday school curriculum, family devotional practice, or culture. The interpretive assumptions embedded in that first encounter become the de facto baseline. When new evidence is presented — a better translation, a historical-critical argument, an alternative theological reading — the mind adjusts from the anchor rather than evaluating the new information independently. The adjustment is almost always insufficient.
This has concrete consequences. A person who first heard Romans 13:1-7 interpreted as requiring absolute obedience to secular government will tend to read subsequent engagements with that text through that frame, even after learning that the same text sustained the Confessing Church in Nazi Germany, the liberation theology tradition in Latin America, and a range of other politically charged readings. The initial anchor does not just affect what one believes — it affects what one even notices as a live interpretive possibility.
- 1Your interpretation of a passage is essentially the same as what your childhood church, pastor, or family taught, and you have never seriously examined it against alternative scholarly readings
- 2When you encounter a different interpretation, your first instinct is to find fault with it rather than to evaluate it on its own terms
- 3You describe the interpretation you first learned as 'what the passage clearly says' and alternative readings as 'what liberals/conservatives read into it'
- 4You find it psychologically difficult to imagine a serious Christian or scholar holding a different view of a passage you feel settled about
- 5When a translation differs significantly from the one you grew up with, you assume the familiar one is more accurate without checking the underlying text
The anchoring bias is implicitly addressed in the biblical emphasis on ongoing examination and growth beyond initial learning. Isaiah 28:10 describes learning as progressive: 'line upon line, precept upon precept.' The author of Hebrews distinguishes between foundational teaching ('milk') and mature understanding ('solid food'), implying that early anchors must be built upon and, in some cases, corrected (Hebrews 5:12-14). Paul's charge to Timothy to 'handle the word of truth correctly' (2 Timothy 2:15) presupposes that incorrect handling — including uncritical dependence on received interpretations — is a real danger. The Bereans' practice in Acts 17:11 of examining even apostolic teaching against Scripture models freedom from anchoring to any human teacher.
Identify your anchor
Ask: What is the first interpretation of this passage I encountered? When, where, and from whom did I first hear it?
Make the anchor explicit. Write down the interpretation you currently hold and try to trace it to its source. Is it from childhood Sunday school? A particular commentary series? A pastor you trust? Naming the anchor does not invalidate it, but it reveals that it is a starting point, not a self-evident truth.
Research the interpretation's history
Ask: How old is this interpretation? Was it the dominant reading in the early church, the medieval period, the Reformation, and modernity — or did it emerge recently?
Check a history-of-interpretation resource such as the Ancient Christian Commentary on Scripture or a scholarly introduction to the book you are studying. If your anchor is a reading that emerged in the 19th or 20th century but is treated as the obvious sense of the text, that gap is worth investigating.
Generate alternative interpretations independently
Ask: If I had no prior anchor, what are the other ways a careful reader might understand this passage?
Consult at least two commentaries from different theological traditions. Note their readings before comparing them to your own. Try to enter each alternative reading charitably and fully before evaluating it against your anchor.
Evaluate all readings on the same evidentiary criteria
Ask: What textual, historical, and contextual evidence does each interpretation offer? Am I holding them to the same standard?
List the primary arguments for each reading. Apply the same level of scrutiny to your anchor's supporting arguments as you do to the alternatives. If the anchor's arguments would not convince you when applied to a different position, they may not be as strong as they feel.
Adjust proportionally to the evidence
Ask: After fair evaluation, what is my considered judgment, and how has it changed from my anchor?
You may conclude that your original interpretation was correct — but you should be able to say why, with reference to evidence rather than familiarity. If your view is unchanged, ask whether that is because the evidence supports it or because the anchor remains too strong to dislodge.
