It's estimated that ~1% of the world's population eats at McDonald's every day.

McDonald's best lever to influence purchase decisions is the menu, which the $190B fast-food chain designs with many psychological hacks to boost sales.

Here are 10 of them 🧵
1/ In the mid-2010s, McDonald's sales were lagging. The brand turned around its fortunes with a multi-year menu & store redesign that:

◻️emphasized simplicity (speeding up avg. drive thru time from 400 secs to 350 secs)
◻️highlights signature items (pricier = higher margins)
2/ Here is McDonald's challenge: loyal customers love the classics (Big Mac, McChicken).

And they spend only 30 secs on the menu (getting them off default options is hard).

But McDonald's sells 2B+ meals a month, so influencing choices for a small % of customers boosts profits.
3/ Attention cues

Dynamic menus were the biggest change. While value items are typically static pics, signature items are animated.

Our peripheral vision specializes in detecting motion. Dynamic signature items capture our attention and end up in our potential choice set.
4/ Decision anchoring

First options are key in decision-making. In a study of buffets, 70% of eaters put one of the first 3 items on the plate.

Signature items are often the 1st thing you see. By highlighting them, they are nudging the higher-margin items into your choice set.
5/ Optimized for working memory

Cognitively, humans can hold 5-9 "items" in our working memory at one time (e.g., 7-digit phone numbers).

McDonald's dynamic menus highlight 7-10 items. Naturally, the majority of the menu real estate emphasizes higher-margin items or combos.
6/ Price anchoring

Even if *none* of the signature item nudges work, we've been exposed to the priciest items on McDonald's menu.

A subsequent purchase from regular (or value) menu will seem like more of a deal based on the price difference...leading to the perception of value.
7/ The power of grouping images

Gestalt principles describe how humans perceive objects and one of them is pattern matching.

McDonald's often groups 3 similar images together of a single product category (usually Signatures) to create a "pattern" that captures our attention.
8/ Health halo

Studies show that menus with healthy food items actually end up pushing people to eat junk food.

Why? The healthy images raise the "health index" of an entire choice set, giving us permission to indulge.

Naturally, McDonald's includes such images on its menu.
9/ Experience chunking

Inside the restaurant, McDonald's separated the order and waiting lines.

The key here is that our perception of "waiting" is reduced vs. if it was a single line. Thus, our memory of the experience is that the wait "wasn't too long".
10/ Self-order kiosks

You've probably used one. While the joke is that McDonald's is making us work, the kiosks are *def* effective at making us spend.

How? We don't feel pressure/anxiety of ordering in line. Instead, we take time and fully customize (=spend more) on the order.
11/ The logo

This isn't part of the redesign but worth flagging: the colors in McDonald's logo are very strategic.

We see color before words and images. And many fast food chains use red, which evokes urgency and desire.

(Research suggests it raise blood pressure/appetites).
12/ If you enjoyed that, I write threads breaking down tech and business 1-2x a week.

The invention of bánh mì is a combination of climate, trade and urban layout of Saigon in late-19th century designed by French colonist.

When the French captured the area in 1859, most economic activity in the region took place along the Saigon river.

The population built makeshift homes tightly bundled by the river banks. Outgrowth from this eventually lead to narrow alleyways between many buildings that is trademark of the city (the Khmer named the region Prey Nokor then French renamed it Saigon and then it was renamed to Ho Chi Minh City in 1976 after end of Vietnam War).

Over decades, the French created European street grids and built wide Paris-type boulevards in the city to funnel commerce to larger markets (also make the city easier to administer).

It was at these markets that French baguettes were introduced and traded.

Bánh mì bread is known for being flaky and crispy on the outside while fluffier on inside (so god damn good).

Two features of Saigon helped create this texture:

▫️Climate: The heat and humidity in Southeast Asia leads dough to ferment faster, which creates air pockets in bread (light and fluffy).

▫️Ingredient: Wide availability of rice meant locals added rice flour to wheat flour imports (which were quite expensive). Rice flour is more resistant to moisture and creates a drier, crispier crust.

Fast forward to the 1930s: the French-designed street layout is largely complete. Now, the city centre has wide boulevards intersected by countless narrow alleyways.

The design was ideal for street vendor carts. These businesses were inspired by shophosue of colonial architecture to sell all types of goods as chaotic traffic rushed by.

Vietnam has some of the most slapping rice and soup dishes, but many people on the move in the mornings wanted something more portable and edible by hand.

Bánh mì was traditionally upper class fare but it met the need for on-the-go food.

Just fill the bread with some Vietnamese ingredients (braised pork, pickled vegetable, Vietnamese coriander, chilies) along with French goodies (pate).

Pair it with cà phê sữa đá (aka coffee with condensed milk aka caffeinated crack) and you’re laughing.Image

Haven’t lived in Saigon for 10+ years but ate a banh mi every other day when I did.

While there, I also sold a comedy script to Fox (pitch: “The Fugitive meets Harold & Kumar set in Southeast Asia”).

It never got made but fun story to retell: readtrung.com/p/im-making-a-…

the most underrated winner of the AI boom is the 15,000 person Caribbean island of Anguilla (which has a GDP of ~$320m) Image
The research team is happy to announce that we’ve played our part contributing to Anguilla’s windfall.

We also paid $99 to GoDaddy to see if we could secure one more .AI domain. Bearly.AIImage
Polynesian island Tuvalu has an even smaller population (10,000)!!

Boston Consulting Group (BCG) trained an AI slideshow maker called “Decker” on 900 templates and apparently gotten so popular that “some of its consultants are fretting about job security.” Image
Sorry, called “Deckster”. That excerpt was from this BI piece that also looked at McKinsey and Deloitte AI uses: businessinsider.com/consulting-ai-…

The Mckinsey chatbot is used by 70% of firm but same anonymous job board said it’s "functional enough" and best for "very low stakes issues." x.com/bearlyai/statu…
Here’s a r/consulting thread based on Computer World last year. Deckster was launched internally March 2024…some think it’s BS…some think it helps with cold start (B- quality): reddit.com/r/consulting/s…Image

Norway discovered off-shore oil in 1969. It launched its sovereign wealth fund with $300m in 1996.

It’s since grown 6,000x to $1.8T or $327,000 per Norwegian (5.5m people).

The fund owns 1.5% of all global equities but, most impressively, had a UX designer put a real-time fund value tracker on its website landing page.
Norway’s SWF roughly is 65% equity, 25% bond, 10% real estate/infra (all global).

Unsurprisingly, its largest holding is Apple ($47B, or 1.4% of the entire company).

On a related note, here is my deep dive podcast on Steve Jobs and making of the iPhone: podcasts.apple.com/us/podcast/caf…
Norway spared no expense on its SWF website. Look at that carousel!
