All I did was drop my master scientist onto the drawing board and while she drew the heathen master scientist came over and watched her until she finished. Then he celebrated and went over onto the mat to think. He had that yellow flashing orb above his head that usually means you can't convert a blue-masked heathen at the moment. After about an hour the orb left and so I repeated the process. I had to do it a total of 3 times before he converted. CherryDrops said they had to do it 5 times. It probably depends on how low the heathen's faith level is. Oh and I had level 2 science.
