Spend some extra time figuring out why they're struggling. But I suspect what you have in mind is something else, something more along the lines of leaving them behind.
It's effectively impossible to get someone with an IQ of 130 to have empathy for someone with an IQ of 95. They just need to work harder, they just need to have better teachers, they just need to stop watching so much television, they just need to get better nutrition, ad nauseum.
Imagine the ego crush that would occur if a 130 IQ true-believer in human equality is faced with the prospect that their intellectual success is due to winning a genetic lottery, not due to their hard work and proper life choices.
Of course they're going to deny the reality of hardwired cognitive horsepower.
To do otherwise is to deny how much better they are than you.
