Well the origins were laudable, it’s just that it was shortly thereafter extended for racist means. Binet and Simon wanted to see if they could devise a test to measure intelligence in children, and they ultimately came up with a way to measure a child’s mental age.
At the time, problem children who did poorly in school were assumed to be sick and sent to an asylum. They proposed that some children were just slow, but they could still be successful if they got more help. Their test was meant to identify the slow children so that they could allocate the proper resources to them.
Later, their ideas were extended beyond the education system to try to prove racial hierarchies, and that’s where much of the controversy comes from. The other part is that the tests were meant to identify children that would struggle in school. They weren’t meant to identify geniuses or to understand people’s intelligence level outside of the classroom.
Yeah, reading the article, it sounds like they’ve decided to park at the space station because the parts that malfunctioned during the journey to the space station were not designed to survive re-entry, meaning that they won’t have the opportunity to understand what went wrong with them after they return to Earth. So they’re delaying the departure in order to collect as much information as possible about what went wrong in the first part of the mission. They’re still confident that a safe return is going to happen.
