Only one of these dub innovators took on the name “Scientist,” but that label fits all of them well. Studio rats like Scientist, Jammy, and Lee “Scratch” Perry used the sturdy, hard-to-fuck-with structure of reggae as their base, then fucked with it a lot, mixing in delay after delay or dropping the beat dramatically just to see what would happen. Their tools were analog, but future researchers like Equiknoxx and Sun Araw brought the scientific method into the DAW era; the opening “Invocation” featuring Araw and the Congos is a highly potent chemical.
