Picture this: you’re walking by a new coffee shop and pause to take a look. Hmm, how can you figure out whether they have good coffee – maybe the # of people inside? Too few customers and you might think “boy, this place probably sucks.” Too many and you’re no longer interested in fighting the crowds for just a cup of coffee.
On the web we’d just multivariate test to find optimum page layout. But the darn physical world is so much more complicated. I threw together a short survey and farmed it out to 100 US consumers via mechanical turk (side note: using turk is addictive). All the usual disclaimers reply WRT survey bias and construction – i know my questions were a bit leading…
Imagine you were going to try a new coffee shop….
1. If the cafe was empty, would that make you more likely to enter, less likely or no change?
No Change: 52%
Less Likely: 26%
More Likely: 22%
2. If this new cafe had good coffee, how many other customers would you expect to see?
> those who answered ‘less likely’ in Q1 avg’ed 14.5
> those who answered ‘more likely’ avg’ed 9.6
0 – 5: 30
6 – 10: 40
10 – 19: 12
3. How many people would need to be in a cafe to make it “too crowded” for you?
> those who answered ‘less likely’ in Q1 avg’ed 30.8
> those who answered ‘more likely’ avg’ed 22.9
0 – 10: 11
11 – 19: 23
20 – 29: 35
So it would suggest that the average cafe owner would want to have ~11 – 19 visible in their cafe to people on the street. Any more than that and you should conceal them in a back room or out of sight of the front windows and register
