I think this is exactly what the article set out to disprove.

> particularly when it involves lots of lives as you risk dehumanisation.

The article stated:

> If people relied on their stereotypes more or less rationally, they would rely on them to inform judgments when they had little or no definitive information, but ignore them when they had definitive information. And it turns out this is just what most people do.

The idea that stereotyping is dehumanising, or used is some way to deny others, or put them in a box is specifically what the article says people don't do.

Instead, the article claims, people use stereotypes to improve the odds when there is no other information. To call that dehumanising is a pretty long bow to draw IMHO.
