| Soleron said: No it's about countability. "Risks" is being used as a plural and hence countable number (one risk, many risks). So fewer is correct. "They have less risk" would be correct, because risk would be used as a collective noun there. |
The countability part refers to measurable units though, i.e. count nouns. A risk does not fall under that category: it's a mass noun. At the least, I don't see how one normally goes around quantifying risks. Here, even though "risks" is plural, it's really being used as a single unit.
