Design Principles
Ability, Benevolence & Integrity (ABI Trust Model)
Perceived trustworthiness is shaped by three independent dimensions: ability (can they do what they claim?), benevolence (do they care about my outcome, not just their own?), and integrity (will they behave honestly and transparently?). A page that fails on any one dimension fails the trust test.
Where it comes from
It comes from Mayer, Davis and Schoorman's integrative model of trust — one of the most cited frameworks in organisational research. They identified three independent factors that determine whether one party trusts another: ability, benevolence, and integrity.
Why it matters for your website
Mayer, Davis and Schoorman's integrative trust model — one of the most cited frameworks in organisational behaviour research — identifies three factors that independently determine whether a person trusts another party: ability (do they have the competence to deliver?), benevolence (are they motivated by my outcome, not just their own gain?), and integrity (do they behave consistently with stated values and tell the truth?). All three must be present for trust to form; the absence of any one is sufficient to break it. Applied to web design, the framework gives a precise diagnostic: prove ability through specific, attributed evidence; prove benevolence by demonstrating understanding of the customer's situation and protecting their interests; prove integrity through pricing transparency, honest limitations, and clear data practices. Generic "we're great" copy fails all three simultaneously.
The three dimensions are independent, and all three are required. Ability is 'can they do what they claim?'; benevolence is 'do they care about my outcome, not just their own gain?'; integrity is 'do they behave honestly and consistently with stated values?' — and the absence of any one is enough to break trust.
Applied to a page, this gives a precise diagnostic. Prove ability through specific, attributed evidence; prove benevolence by showing you understand and protect the customer's interests; prove integrity through pricing transparency, honest limitations, and clear data practices. Generic 'we're great' copy fails all three at once, because it demonstrates none of them.
Wrong vs right
Generic 'we're the best' copy that demonstrates none of ability, benevolence, or integrity.
Specific evidence of competence, genuine care for the customer's outcome, and honest, transparent practices.
Strong proof of competence (ability) but no sign the company cares about the customer (benevolence).
Demonstrating all three: capability, care for the customer's interests, and honesty — since any missing one breaks trust.
Hidden pricing and vague data practices that quietly fail the integrity test.
Transparent pricing, honest limitations, and clear data practices that prove integrity.
Understanding Ability, Benevolence & Integrity (ABI Trust Model)
The ABI trust model, from Mayer, Davis and Schoorman, is one of the most cited frameworks in organisational research. It identifies three independent factors that determine whether someone trusts another party: ability (do they have the competence to deliver?), benevolence (are they motivated by my outcome, not just their own gain?), and integrity (do they behave honestly and consistently with their stated values?).
The key property is that all three are necessary, and they're independent. A company can be demonstrably capable yet seem not to care, or caring yet dishonest — and trust fails in either case. The absence of any single dimension is enough to break it, which is why partial trustworthiness isn't really trustworthiness at all.
Applied to web design, the model becomes a precise diagnostic. Prove ability through specific, attributed evidence; prove benevolence by demonstrating you understand and protect the customer's interests; prove integrity through pricing transparency, honest limitations, and clear data practices. Generic 'we're great' copy fails all three simultaneously. It connects to the hierarchy of trust, the authority principle, and trust signals.
How Kweri checks it
Kweri can assess whether a page provides evidence across the three dimensions — specific proof of ability, signals of benevolence (understanding and protecting the customer), and markers of integrity (pricing transparency, honest limitations, clear data practices) — and flag where one or more is missing. What it can't verify is whether those signals are *true*: whether the competence is real, the care genuine, the transparency complete. So Kweri surfaces gaps across ability, benevolence, and integrity and prompts you to address each, while the authenticity behind them is yours to ensure.
FAQ
What is the ABI trust model?
The ABI model, from Mayer, Davis and Schoorman, identifies three independent factors that determine trust: ability (competence to deliver), benevolence (caring about the other party's outcome), and integrity (honesty and consistency with stated values). All three must be present.
What are ability, benevolence, and integrity?
Ability is whether they can do what they claim; benevolence is whether they care about your outcome, not just their own gain; integrity is whether they behave honestly and consistently with stated values. Together they form perceived trustworthiness.
Why must all three dimensions be present?
Because they're independent and the absence of any one breaks trust. A capable company that seems not to care, or a caring one that's dishonest, won't be trusted. Partial trustworthiness on one or two dimensions isn't enough.
How do I demonstrate trustworthiness on a page?
Prove ability with specific, attributed evidence; prove benevolence by showing you understand and protect the customer's interests; prove integrity through pricing transparency, honest limitations, and clear data practices. Generic 'we're great' copy demonstrates none of them.
Where does the ABI trust model come from?
From Mayer, Davis and Schoorman's integrative model of organisational trust, one of the most cited frameworks in organisational behaviour research. It's widely applied to how trust forms between people and organisations.
Related principles
Trust is not binary — it is staged. Users must have lower-level trust needs met before they will commit to higher-level ones, and demands that outpace the trust already established cause abandonment.
People look to what others do and say to judge the right course of action, especially when unsure.
People defer to credible, knowledgeable sources — credentials and expertise build trust and compliance.
At every point where a user is asked to commit — enter card details, hand over an email, start a free trial — a predictable anxiety spike occurs; unaddressed, it is the direct cause of the majority of checkout and sign-up abandonment.
A visitor must believe the product will work specifically for someone in their situation — generic social proof and large outcome claims do not substitute for evidence that it works for people like them.
