These MRI machines generate a rather strong magnetic field 3-5 T. Even if it is a minimal 0.5 T, natural Earth's magnetic field is much smaller ~5 × 10^(-5) T.

These MRI machines generate a rather strong magnetic field 3-5 T. Even if it is a minimal 0.5 T, natural Earth's magnetic field is much smaller ~5 × 10^(-5) T. Thus for ecological validity they should have checked that MRI MF really does not interfere with the measured brain function.
It can be somewhat ok to solve HackerRank type problems for 30 minutes in such MRI generated field. IRL programming sessions can take up to several hours. And let's see what quality of code would be produced or interpreted for hours in an MF 10000< times stronger than natural. Thus 80% of such neuroscience is non-scalable fragile bs.
