## How to use it

Keep it open during discovery and negotiation calls, and reach for the matching counter-question the moment you notice a prospect's reasoning skew toward one of the fifteen patterns.

## What's inside

- 15 biases covered: anchoring, sunk cost, confirmation bias, status quo bias, loss aversion, recency bias, halo effect, bandwagon effect, authority bias, optimism bias, framing effect, endowment effect, overconfidence bias, IKEA effect, present bias
- One-line definition per bias
- "How it sinks deals" explanation grounded in real buying behavior
- A ready-to-use counter-question for each bias to surface it live in conversation

Each bias below shows up in how a prospect (and sometimes you) makes decisions. Use the counter-question in real conversations to surface the bias and move the decision back onto solid ground.

1. **Anchoring**, The first number or reference point mentioned dominates all judgment after it.
 *How it sinks deals:* Prospect anchors on a low prior-vendor price or an early budget number and can't be moved off it even when the value case is different.
 *Counter-question:* "Before we talk numbers: if budget weren't the constraint, what would the right solution look like?"

2. **Sunk Cost Fallacy**: Continuing to invest in something because of what's already been invested, not because of future value.
 *How it sinks deals:* Prospect stays with an underperforming incumbent because of the time/money already sunk into implementation.
 *Counter-question:* "If you were choosing for the first time today, with no history either way, what would you pick?"

3. **Confirmation Bias**, Seeking information that confirms an existing belief and discounting what contradicts it.
 *How it sinks deals:* Prospect already believes "we can build this ourselves" and only registers evidence that supports that.
 *Counter-question:* "What would have to be true for building this in-house to NOT be the right call?"

4. **Status Quo Bias**: Preference for the current state, independent of whether it's actually better.
 *How it sinks deals:* "No decision" wins by default even when the current state is clearly costing them.
 *Counter-question:* "What does it cost you to keep doing this exactly the way you're doing it today?"

5. **Loss Aversion**, Losses loom larger than equivalent gains; people work harder to avoid a loss than to achieve a gain.
 *How it sinks deals:* Prospect is more moved by "what you're losing by not acting" than "what you'll gain", reps who only pitch upside miss this lever.
 *Counter-question:* "What's it costing you every month this stays unsolved?"

6. **Recency Bias**, Overweighting the most recent event or data point.
 *How it sinks deals:* A single recent bad experience (with your category, not necessarily you) colors the whole evaluation.
 *Counter-question:* "Is there something recent that's shaping how you're thinking about this?"

7. **Halo Effect**: One positive trait (a slick demo, a big logo reference) makes everything else look better than it is.
 *How it sinks deals:* Works against you when a competitor's brand or polish outshines your actual fit; works for you if you lean on the wrong single impression instead of substance.
 *Counter-question:* "Beyond the [demo/brand/reference], what specifically needs to be true for this to work for your team?"

8. **Bandwagon Effect (Social Proof)**, Doing/believing something because others are.
 *How it sinks deals:* Prospect waits to see what "everyone else" does before deciding, stalling the deal indefinitely.
 *Counter-question:* "Setting aside what others in your space are doing, does this solve your specific problem?"

9. **Authority Bias**: Overweighting the opinion of a perceived authority figure, regardless of relevance.
 *How it sinks deals:* A single senior voice (internal exec, analyst report) with limited direct knowledge derails a well-reasoned team consensus.
 *Counter-question:* "What's driving [authority]'s view, have they seen the details we've walked through?"

10. **Optimism Bias**, Believing you're less likely than others to experience a negative outcome.
 *How it sinks deals:* Prospect underestimates the risk/cost of staying with a failing status quo ("it probably won't get worse").
 *Counter-question:* "If this trend continues at the same rate, where does that leave you in 12 months?"

11. **Framing Effect**, The same information leads to different decisions depending on how it's presented (gain vs. loss, percentage vs. absolute).
 *How it sinks deals:* A prospect rejects a price framed as "cost" that they'd accept framed as "investment relative to the problem's cost."
 *Counter-question:* "Does it help to look at this as cost-per-[unit relevant to them] rather than the total number?"

12. **Endowment Effect**, Overvaluing something simply because you already own/use it.
 *How it sinks deals:* Prospect overvalues their current tool/process purely because it's theirs, independent of actual performance.
 *Counter-question:* "If you didn't already have [current tool], would you build/buy it again today?"

13. **Overconfidence Bias**, Excessive confidence in one's own judgment or ability to execute (e.g., "we'll just build it ourselves").
 *How it sinks deals:* Prospect overestimates internal team's ability to deliver a DIY alternative on time and budget.
 *Counter-question:* "What's your track record on projects like this hitting their original timeline?"

14. **IKEA Effect**: Overvaluing something you built yourself, disproportionate to its actual quality.
 *How it sinks deals:* An internal, homegrown solution is defended past the point it's still serving the business, because someone built it.
 *Counter-question:* "If a new person joined the team tomorrow with no attachment to what's built already, what would they recommend?"

15. **Present Bias (Hyperbolic Discounting)**, Overweighting immediate cost/effort against larger future benefit.
 *How it sinks deals:* Prospect delays a clearly-positive-ROI decision because the switching effort is felt now and the payoff lands later.
 *Counter-question:* "What would make the next 30 days of switching cost feel worth it against the next 12 months of payoff?"
