Same request, same model, once with the skill and once without. Read both and judge for yourself.

“Our meal-kit signup has 4 steps and 68% of people drop off at step 3. Any ideas, from a psychology angle, for why and what to change?”

Source material given with the request

Step 1: enter zip code. Step 2: pick plan size (2 or 4 people). Step 3: choose 5 meals from this week's 40 options; you can't continue until 5 are picked. Step 4: payment.

# Why step 3 is probably losing people Step 3 is a cliff in effort. Steps 1 and 2 take seconds and need no thought. Step 3 asks for 5 decisions among 40 options before the person has committed anything. Several biases stack up here: - **Paradox of choice / Hick's Law:** 40 options is a lot of cognitive load, and it's the first real decision in the flow. - **Activation energy / BJ Fogg:** Motivation is still moderate (they're just exploring), but ability has dropped sharply. Low ability plus modest motivation means no action. - **Regret aversion:** "What if I pick wrong and hate them?" They're choosing food for a service they haven't tried yet, so every pick feels risky. - **Hard gate:** Being unable to continue until exactly 5 are picked turns a decision into a chore. It also removes the sense of control. - **No investment yet (commitment & consistency):** The IKEA effect only helps once people feel invested. At this point they've only given a zip code and a plan size, so quitting costs them nothing. - **Possible price surprise:** If they don't see per-serving or total price until step 4, step 3 is also where the "is this worth it?" doubt builds up with no answer. # What to change **1. Use defaults (Default Effect / Nudge Theory)** Pre-select 5 meals, such as "most popular" or "chef's picks", and let people swap them. This changes the task from building a selection to editing one. It's likely your highest-impact test. **2. Cut the choice set (Hick's Law)** - Show 8–12 curated meals first, with "See all 40" as a secondary option. - Add filters (vegetarian, under 30 min, family-friendly, etc.). - Add tags like "Most popular" and "New", which also bring in social proof.

**3. Add a quick preference step earlier** Ask 2–3 questions (dietary needs, foods they dislike) after plan size. This is a small commitment that makes the later meal list feel personalized, and it filters the 40 options down to relevant ones. **4. Remove the hard gate** Let them continue with fewer than 5 picks and auto-fill the rest ("We'll choose for you, change anytime before [cutoff date]"). Or test moving payment before meal selection, so meals become a post-commitment customization. Exit rates tend to drop once people have paid. **5. Reduce regret (Regret Aversion)** Near the selection, say things like "Swap meals anytime before [date]", "Skip any week", and "Cancel anytime." Add ratings or photos of real dishes. **6. Give a sense of progress (Goal-Gradient)** Add a counter like "3 of 5 picked" with a progress bar, and keep the 4-step bar visible. People speed up as they approach a goal. **7. Show price earlier (Anchoring / Mental Accounting)** Show the per-serving price at plan selection and a running total on step 3, for example "$8.99/serving, first box 50% off". That removes the surprise before step 4. # Check the basics before redesigning Following Occam's Razor, rule out simple causes first: - Does step 3 load slowly (40 images) or break on mobile? - Is the 68% drop worse on mobile than desktop? - Do people pick 3–4 meals and then leave? That points to the hard gate. If they leave with 0 picks, it points to overwhelm or price. - Do session recordings show scrolling and hesitation or an instant exit? - Are the meals shown actually available for their zip code and plan? # Suggested test order 1. Pre-selected defaults with a swap option (smallest change, likely biggest lift). 2. Curated shortlist with filters. 3. Allow continuing with auto-fill, or move payment earlier. 4. Price visibility and regret-reducing copy. If you can share device split and how many meals people have picked when they exit, I can narrow down which of these is most likely your real culprit.

## Why step 3 is probably the cliff **1. Choice overload plus a hard requirement.** Picking 5 from 40 is a big comparison task, and the "can't continue until 5" rule makes it feel like a test you can fail. Choice overload is strongest when people don't yet know their preferences and no option stands out, which describes a first-time visitor. **2. Effort before commitment.** Steps 1 and 2 take seconds. Step 3 is the first real work, and it comes before the user has invested anything (no account, no payment). There's no sunk cost holding them in. **3. It's the first real product exposure.** This is where people see what the food is, what it looks like, and maybe what it costs. Drop-off here may be partly "I'm not sold" rather than "this is hard." **4. Fear of commitment.** "This week's meals" signals that this will be a recurring chore. Users may wonder whether they have to do this every week, whether they'll be charged immediately, and whether they can change their picks. **5. Maximizer anxiety.** With 40 options, people worry about picking the wrong ones and wasting money. The easy way to avoid that regret is to leave. **6. Possible mobile friction.** Scrolling through 40 cards on a phone is much worse than on desktop. ## What to change (roughly in order of expected impact) 1. **Pre-fill 5 meals.** Show a default selection ("Our most popular this week") with a swap button on each. Editing a default is far easier than building from scratch, and defaults are one of the strongest behavioral levers. 2. **Ask 2-3 preference questions in step 2.** Examples: dietary needs, foods you dislike, and quick vs. adventurous. Use the answers to filter or rank the 40 down to about 10-15 and pre-fill from that. The questions also create a small investment and feel personalized. 3. **Add filters and categories** (vegetarian, under 30 min, family-friendly) if you keep the full menu visible. 4. **Remove the hard gate.** Offer "Choose for me" or "I'll pick later; we'll send a

reminder and auto-select before the cutoff." Letting people skip the decision costs less than losing them. 5. **Make progress and reversibility visible.** Use a sticky tracker ("3 of 5 chosen"), and add copy like "You can change meals until [date]," "Skip or cancel anytime," and "You won't be charged until the next step." 6. **Slim down the cards.** Use a big photo, a name, time, and 1-2 tags, with details on tap. Show price per serving here if you don't elsewhere. 7. **Capture an email earlier** (step 1 or 2) so you can send recovery emails to people who abandon at step 3. ## Diagnose before you build - Look at how many meals people had selected when they left. If most leave with 0, it's overwhelm or lack of interest. If most leave at 3-4, it's the hard gate or not finding meals they like. - Segment by device, traffic source, and time on step. - Check scroll depth and filter use. - Rule out bugs or slow image loading. - If you can, run a few user tests or a one-question exit survey ("What stopped you?"). ## What to A/B test first - Pre-filled meals vs. empty - Preference questions + curated shortlist vs. full 40 - "Choose for me" option vs. none I'd expect the pre-fill test to move the number the most. The preference-question test is the most informative about why people leave.
