A variation of this hack which is used by my local car wash: Buy a booklet of 10 pre-paid vouchers for the car wash and get a free car wash ... right now.
According to the owners, moving the 'free' car wash to be immediately available rather than at the end of the voucher book say a significant increase in people who bought them - even though ultimately it made no difference financially to the customers.
It's exactly the same thing as selling someone 11 pre-paid car washes. But by making the 11th car wash "free" and available immediately people perceive that as a bigger boon than a 9% discount.
Another way to make the task seem less daunting is to make the card vertical, presenting four rows (of three stamps each) to complete instead of two rows of six.
Grouping focuses people on immediate completion (visually completing a line or block) and keeping the relevant numbers small (3 and 4 instead of 12), even if the groups have no nominal significance.
I wonder if actually making the rows early-redeemable, for less than the proportionate total reward, could also help.
For example, in a 4x3 card, maybe each row of 3 gets you 15% off if redeemed early. In this way, you're always close to something with provable value; you're more likely to value/carry/protect the partially-completed card; but you're also still likely to go for the 12-for-100%-off rather than stopping at 3-for-15% / 6-for-30% / 9-for-45% off.
(The various App punchcards bring the possibility of running many more incremental tests in this area, and novelties like 'awakening' dormant customers with a gifted stamp or two.)
This is also known as the Endowed Progress Effect. A paper from 2006 discusses it in a fairly easy to read format.
Extract: "This research documents a phenomenon we call the endowed progress effect whereby people
provided with artificial advancement towards a goal exhibit greater persistence towards reaching
the goal. By converting a task requiring eight steps into a task requiring 10 steps, but with two
steps already complete, the task is reframed as one that has been undertaken and incomplete
rather than not yet begun. This increases the likelihood of task completion and decreases
completion time. The effect appears to depend on perceptions of task completion rather than a
desire to avoid wasting the endowed progress. Moderators include the reason, if any, offered for
the endowment, and the currency in which progress is recorded."
I took a grad level marketing class as an undergrad in my time at my university and remember my professor mentioning this very same paper. Always found it fascinating, and at the time I was working at a bakery part time as well. Pitched the idea to them, they implemented, but the gains were marginal. Although, I suspect because business went down simultaneously during that period that no gain or no noticeable change could be seen as something of a positive, because everything else was in decline. So, yeah, I guess you would say it has real world application.
its also a really easy to demonstrate idea. I bring it up every time i encounter a loyalty card, just because I find it so damn interesting and remember the exact moment that my professor told us about this, eye opening example.
One thing that comes to mind- you would probably want a period of time where the 12-mark card has no prefilled marks, so that customers adjust. If you switch directly from 10-mark to 12-mark with two prefilled, the trick is a little more apparent.
Is there a limit to how steep on the gradient you can go with this? If you give someone 900 out of 1,000 will they be rushing to fill in that last 100 because they've only got ten percent left on the card? Or is it limited to easily foreseeable goals in the single digit or near to that range?
My guess would be that the 12 is already near the limit. The two "free" stars feel like a little personal gift, especially if they actually punch them out when they give them to you, with a sly wink or something. If it was 900/1000, it would feel confusing and dishonest.
You might also gain some actual loyalty if you give them the last one for free, since that would be an unexpected treat reserved for people who bought 9 cups of coffee.
It could be related to risk and energy expenditure. Moving faster requires more energy, and the farther away your piece of cheese is, the more likely it is that something unexpected might happen to take it away/stop you before you get to it.
Add to this that there can always be more pieces of cheese to find, and always running from one to the next one could not be your best course of action.
It's also that short distances are more accurately judged than long ones (ditto endurance over short distances). There are often sprints to the finish in running races when there's a final surge of adrenaline, when you realise you can sustain an increased pace all the way to the end.
Personally I'm not sure how effective loyalty cards can be. I prefer to shop places where the perceived prices are reasonable over shops that offer big discounts through loyalty programs (e.g. Trader Joe's vs. just about any supermarket chain). The reasoning is that I prefer the freedom to do without mental calculations over rewards programs over actual dollar savings. That is, I'd rather pay more not to have to think about cards, stamps, rewards, etc.
"Your expected wait time is 45 minutes..." And then after a brief moment, the same voice comes on and says "We've cut your time in half. It's just 20 minutes now!"
There's been some fun research done on the topic of progress bars and user perceptible wait times. (To the surprise of absolutely no-one who is paying attention, a) people suck at math and b) if one has accurate knowledge that a process will take 100 units of time, coloring in 1% of the bar per unit of time is provably suboptimal with respect to user happiness.)
Disneyland does something like this with wait times for attractions.
According to a 1989 Newsweek article:
The waiting times posted by each attraction are generously overestimated, so that one comes away mysteriously grateful for having hung around 20 minutes for a 58-second twirl in the Alice in Wonderland teacups.
Always a nice moment when that happens. Though I believe your talking more about "under promise - over deliver" rather than applying a sort of progress to a certain goal. Always use "under promise - over deliver" when possible, your customers will love you for life :) (exception: DMV)
Like loading screens that go faster near the end? I don't know that making the wait time look worse than it already is (40m vs 30m) will please customers.
I agree - for a once in a blue moon interaction, sure, not having to wait as long as you originally thought might be good.
For any kind of interaction which may be repeated then it just makes you look like a stupid business owner or software developer who can't properly estimate how long something will take!
I'm not sure that's true. One case that comes to mind is World of Warcraft server queues. In general, waiting in a queue to log into a server is something a player does either daily or never, and people really like to comment on their very exciting experience in the queue once they finally get in. In several years, I don't remember ever seeing a negative comment about how the queue didn't take as long as the initial estimate and in fact there were often positive comments when that happened. On the other hand, when the initial estimate was too low, people frequently complained about how bad Blizzard was at providing estimates.
I've experienced this while running- on the last lap, I suddenly feel relief and a rush of energy (or lack of tiredness). I always attribute it to a desire to tough out the last bit so I can get to a greater relief.
Starbucks cards are great. My JP card only gives me ANA miles (1/dollar spent, so pretty much nothing) but in NYC... there's one everywhere, so I'll get my tea to walk, get to the next store and get a croissant to eat in the park, then continue on to the next to buy the paper. Maybe another tea when I'm about to leave. That's 4 stars for $8. Then when you get your coupon, Trenta all the way. And don't forget the free refills on your smaller drinks (you get one refill per drink).
Apply this to programming, and it's easy to see why people using frameworks and libraries progress further faster: A number of of goals are reached by just spinning up the framework and installing a few gems.
If a coffee shop is doing this deliberately to manipulate you, is it therefore ethical to give the illusion of progress to the coffee shop in turn, by stamping a couple yourself?
This is an interesting question, but I think a bright-line distinction is fairly easy to make.
It's not unethical to try to influence someone, even subconsciously, even by the choice of arbitrary design elements ("you start with 2 of 12 checked") -- as long as there's no deception. Introducing deception crosses the ethical line. So faking a purchase that was never made to gain a benefit is unethical.
Perhaps there's a bit of grayness in that the 2/12 stamps makes people prone to underestimate the magnitude of the remaining effort ("5/6ths remaining") compared to an absolute measure ("10 of 10 purchases remaining"). But without there being a misrepresentation -- for example, a claim that the first 2 stamps are a special favor not usually granted -- all info for a proper evaluation is available and truthful. And it's even possible that such an influence is to the consumer's net benefit: maybe there's another cognitive bias against completely-unstarted efforts, causing people to overestimate effort required and never get started on things they'd actually enjoy. In any case, once the alternatives start requiring discussion or even controlled study to evaluate, it's harder to apply a stark label like 'unethical'. That label is more useful on easier-to-evaluate actions like prima facia deception.
(Still, the point is well taken that these are some sort of continuum, and it might be the case that a certain superficially-truthful offering is so likely to be misinterpreted by an average reader/listener that it is still de facto deception. I don't think the reward-stamps case is anywhere near that line... but carefully-wordsmithed political ads, designed to create false impressions without being blatantly falsifiable, often go right up to and over the line.)
> It's not unethical to try to influence someone, even subconsciously, even by the choice of arbitrary design elements ("you start with 2 of 12 checked") -- as long as there's no deception
I feel your statement is too pat. Why is that not unethical? Based on what ethical pattern?
If the basis of ethics is being truthful, it would seem that ease of understanding is also an important part of ethics. Subconscious manipulation and influence seems to be at odds with that goal.
Perhaps such manipulations is inevitable in a marketplace where everyone engages in unethical mental manipulation, but that does not make it ethical.
But do we even know the 2/12 variant is worse on "ease of understanding"? Maybe it's more understandable, and congruent with the buyer's real best interest, because it's not subject to an endpoint/inertia-of-zero bias that depresses sales from the 0/10 case.
Note that these same sorts of perceptual influences are also the basis for all the do-gooder initiatives that get proposed by Richard Thaler and Cass Sunstein in Nudge. (So in fact I would grant there is at least one more dimension beyond deception: is the influence clearly against someone's interest? But there should be no presumption that whatever they would have done without the influence was the purest expression of their interests.)
Part of my ethical criteria is: what rules work? Part of 'work' is that they are evaluable. An accusation of undue influence, even though every observable aspect of a communication is true and fully disclosed, is very hard to evaluate. It's not very useful as a rule for deciding what one can do, or for assessing 'guilt' after the fact.
Using a bit of communication that is false on its face is easy to evaluate. It's fraud, and it's clearly unethical.
'Manipulation' is a loaded term. It just means "influence we don't like". In a commercial setting, reasonable people already assume a seller is crafting their communication to increase sales. Calling cleverly-crafted commercial influence 'unethical manipulation', even when it remains true in all observable aspects, overloads and dilutes the idea of what's ethical.
Is A/B testing that results in color, wording, and layout changes that increase sales 'unethical manipulation'? Perhaps if it goes so far, in total effect, as to create a tangibly false idea in the customer's minds. But not simply because it incrementally nudges someone towards a purchase.
It's not unethical to try to influence someone, even subconsciously, even by the choice of arbitrary design elements ("you start with 2 of 12 checked") -- as long as there's no deception.
In the simple case this is usually true, but I do wonder when you start throwing millions of dollars at researching exactly this sort of influence and start looking at pavlovian trigger mechanisms and stuff like that.
Most people aren't trained confidence tricksters, stage magicians or professional psychologists, but modern marketing at its most sophisticated is the combination of all three, backed with vast wealth and global reach, and it has already long gone beyond any pretence of acting as a way of informing people of things they might like to buy and has instead attempted, with a lot of success, to become the product itself. And, in case anyone was in doubt, I do not entirely regard this as a good thing.
Maybe if you were shoplifting occasional penny sweets.
Was just meaning there has to be a limit to how far this kind of thing can be pushed without getting downright dodgy in and of itself, and outright psychological manipulation for profit can reach a level where it is really not much better than theft.
I don't think that adding a couple of stamps to a loyalty card is particularly bad, and was just joking to make a point, but the pathological obsessiveness of modern marketing and the way that it can feed back into a mindset of treating your customers as punters or even prey, is something that I think is pretty destructive in our current culture.
[edit] I just realised the above is readable either way. I was meaning that I don't think that the shop adding a couple of extra stamps is really that bad. Obviously adding them yourself is nicking coffee and is only remotely acceptable when either dying of thirst, or possibly when visiting starbucks. :)
