Are there any safety risks associated with receiving an mRNA vaccine (Pfizer or Moderna) after already having received the J and J vaccine? I ask because I know they use different platforms ( mRNA vs adenovirus vector) Signed by 67.253.78.55 talk at 00:51, 30 May 2021.
I was reading in the news a few days ago that a young girl (I believe, age 2) was admitted as a member of Mensa, due to having an IQ of 146 (or so). I was wondering: how do "they" (the scientists, the test examiners, etc.) go about determining the IQ of children so young? And do these methods/scores have any merit or validity? Thanks. Joseph A.

Historically, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age. The implication (roughly, given that modern definitions differ), is that a two-year-old would get a score of 150 by having the mental abilities of a three-year-old. So not so impressive, perhaps. According to Mensa's website
To become a Mensan, all you need to do is demonstrate you have an IQ in the top two per cent(presumably of your age cohort), so that at any age it is possible to join them. Mike Turnbull ( talk) 15:56, 31 May 2021 (UTC)
They made me take the WISC test as a kid several times, due to trouble at school. I don't remember it having reading questions, though it might have had some. It had dexterity tests (arrange wooden blocks with triangles on top so they show specific geometric shapes), a digit span test (they read you digit strings of increasing lengths to see how many you can remember, which was very easy during my era, in which kids were used to remembering phone numbers because they didn't have cell phones with speed dialers), and ISTR some math related tests ("what do the numbers 36 and 49 have in common?" (both are squares)). The last one might not have made sense for really little kids. The main thing I remember is that the dexterity puzzles became a lot easier once you figured out the trick of ignoring the shapes and just figuring out how to place each block separately. So the second time I took the test, I already knew the trick and did a lot better than the first time. I have no idea whether that got me out of trouble in school, or into more trouble. 2601:648:8200:970:0:0:0:752 ( talk) 20:43, 31 May 2021 (UTC)
IQ tests are a load of rubbish IMO. The I stands for Intelligence but really it's a very specific kind of problem solving. When I was a kid we all took the national IQ test, and they told my mother that I achieved the second-highest score in the northwest of England. That would imply that I am (or was) one of the most intelligent people in the country! Well, I'm clever enough to know that that simply isn't true. Sure, I was precocious - I enjoyed reading encyclopedias and even managed teach myself to programme a computer when I was 7 - but I'd argue that it was having access to books and a computer that prepared me for the test. A lot more kids might have scored more highly than me given the same opportunities. I'm arguably highly intelligent but I'm no genius! nagual design 19:02, 1 June 2021 (UTC)
the eleven-plus was redesigned during the 1960s to be more like an IQ test. That meant that, as commented by 2601:648:8200:970:0:0:0:752 it became much easier to do well by rote: practising on the types of question asked. To my surprise, this way of getting good grades in exams: by doing homework mostly consisting of answering earlier year exam questions, still worked right through a university degree.
