"The correlation between the two factors is therefore weak, although statistically significant."
Two qualities having a correlation does not imply that they have a direct cause and effect relationship.
Just because something is statistically significant, doesn't mean the results can be generalized to the population of interest, it just means that whatever results that had occurred from whatever study were most likely not due to chance.
I wouldn't consider height to correlate with intelligence.
I would consider that height does have something to do with inner confidence or just confidence in general.
