MS and red-facedness poll

In a recent post, I suggested that people take a poll at an MS blog to increase the range of data about a possible connection between problematic brain veins and MS. However, you need to register to reply there, and this is probably more trouble than it's worth to answer a single question, so I've replicated their poll here.

Date: 2009-11-24 11:30 pm (UTC)Apparently people who look at me a fair amount can realize I may be pale, or may be blushing, but not with any certainty. So color is just not a good way of judging these things for (at least) my skin tone.
Maybe just saying "does blood rush to your face" is a pretty race-neutral way? Not that you can change the original poll, and I realized you copied it over rather than coming up with it yourself, just figured it'd be a good thing to point out :)

The point of the survey is to have a quick, cheap way to identify possible blood flow differences between people with and without MS as a clue to whether scientific study is worth doing.
My guess is that people can generally feel it in their faces when they blush, but exercise is too distracting to feel whether there's a head/body difference in flushing.

Date: 2009-11-25 12:47 am (UTC)My tentative solution is to go with "redder/darker" on the assumption that there are people whose skin is dark enough that a flush isn't especially red, but that there are a lot of people have skin that's too dark for this sketchy test to be useful.

Date: 2009-11-24 09:41 pm (UTC)* 0 = 1cm
* 2 = 3cm
* 15 = 16cm
Therefore, 2 / 3 = 0.
To be a little bit more constructive, why don't they just use a little red dot or "|"?
I think I'll post this on the LJ blog as well.

Update: Could you modify it to "redder/darker" or "redder or darker" if you prefer? See above for the reasoning.

If all values on the graph are much larger than 1 the effect is negligible, but with small values like these it looks quite anomalous: the bar for 0 is 1/3 as long as a bar for 2, and half as long as a bar for 1. That tells your perception that 3x0 = 2, and 2x0 =1. That's WRONG.

Date: 2009-11-25 04:52 am (UTC)'Redder or darker' is about what color a person's face might turn. Their skin color is going to affect how much difference increased blood flow makes.

Date: 2009-11-25 08:37 pm (UTC)Everyone's head will get a little redder, especially the cheeks, when they exercise, but so too will their body. this doesn't count. By red head, what the poll is looking for is the whole head, and enough that it's obvious or even embarrassing.
Admittedly I am fair skinned, so I appologize if the wording didn't take skin color into consideration as well as it should have.
So far combined total for all sites with this survey:
MS - Yes: 34
MS- No: 9
NotMS yes: 6
NotMS No: 26
Of people with MS 79% get a very red head
Of people wihtout, 77% do not
So far pretty good results confirming Dr Zamboni's thesis!!
