I like numbers. I always have. This is just luck, I think. I see, how helpful it is to have a good understanding of numbers. Failing to develop a facility with numbers results in many bad decisions, it seems to me.
A new article published in closed anti-science way, sadly (so no link), examines how people who are numerate (like literate but for number—understand) process information differently so that they ultimately make more informed decisions. Cancer risks. Investment alternatives. Calories. Numbers are everywhere in daily life, and they figure into all sorts of decisions.
People who are numerate are more comfortable thinking about numbers and are less influenced by other information, says Ellen Peters of Ohio State University (sadly Ohio State allows research by staff paid by them to be unavailable to the public – sad), the author of the new paper. For example, in one of Peters’s studies, students were asked to rate undergraduates who received what looked like different test scores. Numerate people were more likely to see a person who got 74% correct and a person who got 26% incorrect as equivalent, while people who were less numerate thought people were doing better if their score was given in terms of a percent correct.
People make decisions based on this sort of information all the time. For example, “A lot of people take medications,” Peters says. Every drug has benefits and potential risks, and those can be presented in different ways. “You can talk about the 10 percent of the population that gets the side effect or the 90 percent that does not.” How you talk about it will influence how dangerous the drug seems to be, particularly among people who are less numerate.
Other research has shown that only less numerate people respond differently to something that has a 1 in 100 chance of happening than something that has a 1 percent chance of happening. The less numerate see more risk in the 1 in 100 chance—even though these numbers are exactly the same.
“In general, people who are numerate are better able to bring consistent meaning to numbers and to make better decisions,” Peters says. “It suggests that courses in math and statistics may be the educational gift that keeps on giving.”

Encouraging Curiosity in Kids
Posted on October 28, 2011 Comments (7)
How do you help make your children scientifically literate? I think the biggest thing you can do is encourage curiosity.
One way to encourage curiosity it is by answering their questions (and not saying: I am too busy, don’t bother me, don’t ask me?, stop asking why…). I know adults are busy and have all sorts of stuff we are trying to get done; and the question about why I need to wash my hands doesn’t seem worth answering. But I think anytime a kid is asking why is an opportunity to teach and encourage them to keep being curious.
It is very easy to shut off this curiosity, in our society anyway (we do it to the vast majority of people). The biggest difference I see between adults and kids is not maturity or responsibility but curiosity (or lack thereof in adults) and joy (versus adults who seem to be on valium all the time – maybe they are).
As they grow up kids will have lots of science and technology questions that you don’t know the answers to. If you want them to be curious and knowledgeable, put in the effort to find answers with them. You have to help them find the answers in a way that doesn’t turn them off. If you just say – go look it up yourself (which really they can do), maybe the 2% that are going to become scientists will. But most kids will just give up and turn off their curiosity a little bit more (until eventually it is almost gone and they are ready to fit into the adult world). Which is very sad.
Once you get them used to thinking and looking things up they will start to do this on their own. A lot of this just requires thinking (no need to look things up – once a certain base knowledge is achieved). But you need to set that pattern. And it would help if you were curious, thought and learned yourself.

While walking in the park, see one of those things you are curious about and ask why does…? It is good to ask kids why and let them think about it and try and answer. Get them in the habit of asking why themselves. And in those cases when no-one knows, take some time and figure it out. Ask some questions (both for yourself – to guide your thinking – and to illustrate how to think about the question and figure things out). If you all can’t find an explanation yourselves, take some time to look it up. Then at dinner, tell everyone what you learned. This will be much more interesting to the kids than forcing them to elaborate on what they did today and help set the idea that curiosity is good and finding explanations is interesting.
It is fun as a kid if your parent is a scientist or engineer (my father was an engineering professor).
You often don’t notice traits about yourself. In the same what I know what red looks like to me, I figure we both see this red shirt you see the red that I do. But maybe you don’t. I tend to constantly be asking myself why. If I see something new (which is many, many times a day – unless I am trapped in some sad treadmill of sameness) I ask why is it that way and then try and answer. I think most of this goes on subconsciously or some barely conscious way. I actually had an example a few months ago when I was visiting home with my brother (who is pretty similar to me).
As we were driving, I had noticed some fairly tall poles that seemed to have really small solar panels on top. I then noticed they were space maybe 20 meters apart. Then saw that there seemed to be a asphalt path along the same line. I then decided, ok, they are probably solar panels to power a light for the path at night. Then my brother asked why are there those small solar panel on top of that pole?
