Subject: Re: the no peeking rule for weight loss contracts
Bethany: actually that’s the version in the current contract template:
your official weight for the day is the average of all the scale
readings you report. (And it’s a rule that you report all of them –
which of course is all automatic if you have a withings scale.)
As you know, whether the official weight of the day is the mean or the
min or the median (or any other crazy aggregation function we might
want) is now a parameter setting so it will be easy to experiment with
this. But after discussing to death with Melanie, it seemed like the
mean was the best compromise based on our experience so far.
Jill’s proposal sounds smart, except that I’m really reluctant to
introduce the messy fine print that comes with that. About what counts
as “on vacation” or “access to the scale”. Plus there are so many
legitimate reasons to miss a weighing (overslept, forgot and drank
water before weighing yourself, stayed up all night grazing on swiss
cake rolls, etc) that I’m worried that any reasonable-seeming
threshold like “5 out of 7 days” will sometimes be too strict.
Alex, great point about thinking of this in terms of the akrasia
horizon! (Like we promised, more on that soon!)
Another core tenet of Beeminder that I’ve been harping on for a while
and that Jill just found a great way to express:
Rule #1 of Beeminder: Things that make staying on the road easier
make reaching your final goal harder.
If that sounds counter-intuitive, imagine the extreme case of ultimate
leniency where we’re like “don’t worry, as long as you’re at your goal
weight a year from now all deviations from the road will be forgiven.”
That completely destroys all the benefit Beeminder had to offer!
(Except for those non-akratics who just like the visualization and
tracking, but this list is for akratics. Yellow brick roads without
meaningful commitments are useless for us.)
Peeking is the same way. Sure, if you can peek at your weight before
recording it then it’s much easier to stay on your road. To stay on it
today, that is. But it’s that fear that this piece of pie might put
you over the edge tomorrow that keeps you in check. If that danger is
always at least 3 weeks away, it’s just not immediate enough to
counteract the immediate deliciousness of the pie.
I think the 3-week rule goes nicely with the no-peeking rule because
without peeking you really don’t want to drive blind unless you have
to (like you’re actually on vacation).
If the no-peeking rule is really not realistic then we have to rethink
the 3-week rule.

Well, we originally had a “first weight of the day is the official
weight” rule, and that definitely incentivizes you to cheat.
One proposed way to fix it is to, for example, use an average of your
daily weights, which makes it a lot less risky to report, but it could
also make you more likely to do stupid things like try to drop a
bunch of weight by dehydrating yourself or something, so maybe there’s
a better solution/tradeoff to make.

I think Melanie and Laurie (with $600 and $5k on the line,
respectively, for their weight loss graphs) don’t agree with the no
peeking rule [1].
I think their claim is that it’s too tempting to “unofficially check”
how you’re doing and that it feels unfair and unenforceable anyway.
I wonder if there’s a way to have the best of both worlds here.
Without a no peeking rule you lose a lot of the point of the yellow
brick road. If you can freely peek then you’ll never report when
you’re above the road. Which just means the “daily commitment” thing
has lost all its bite. It degenerates to “you better weigh X pounds by
3 weeks from now”. (Three weeks being the longest you can not report
before losing by default.)
[1] The no peeking rule is clause 3 in the standard contract template:
Standard Beeminder Contract
Also, if you want to cheer Melanie and Laurie:
weight – mo – beeminder and weight – laur – beeminder
