Using LEGO to test children's ability to visualize and rotate 3D shapes in space:
Researchers at the University of California San Diego have developed a test that uses children’s ability to assemble LEGO pieces to assess their spatial visualization ability. Spatial visualization is the ability to visualize 3D shapes in one’s mind, which is tied to increased GPAs and graduation rates in STEM college students.
At the college level, a widely used assessment is the Purdue Spatial Visualization Test: Rotations, or PSVT:R, which is a 20-minute timed test consisting of a series of multiple-choice questions that are geared towards students 13 and older. Van Den Einde and Delson wanted to develop an assessment that would be more suitable and engaging for students at lower grade levels. They turned to LEGO, which was designed with that younger age range in mind and is familiar to many children. To pass the test, students have to assemble a set of LEGO pieces into a specific shape, such as a whale or a small plane, while only being given a picture of the final shape but no step-by-step instructions. The time it takes students to build the correct solution is the metric used for assessment.
[...] In order to validate the test, the researchers had students in two freshman engineering graphics courses take both the LEGO assembly test and the PSVT:R. Students took the tests both at the beginning and end of the quarter. During the course, they were trained with the Spatial Viz app. Test results show a statistically significant correlation between outcomes on the LEGO test and the PSVT:R.

They were, a large part of why is that the precision on them was much better than on the knock offs. Take bricks from pretty much any set back to the earliest plastic ones and they all fit together. The colors are probably still just as good as they were. The sets I have going back to the '80s are more or less just as good as they were when new and show no signs of discoloration or deterioration.
Interestingly, as they've automated more and more of the process, the prices seem to have largely stagnated, meaning that you're paying more or less the same amount now that you were decades ago. The main thing that's changed, is that the upper limit on the number of pieces in a set is much higher than it used to be. Some of those sets have thousands of pieces.
