Reader comments of the week:

On the Medicine & Health channel, Orac discusses a contentious issue, sure to become more prominent as more parents buy into anti-vaccinationist claims, in Mixing unvaccinated children with vaccinated children: Whose rights prevail? Because no vaccine is 100% effective, even one unvaccinated child in a group puts the rest at risk. But parents who refuse to vaccinate their children insist that they are being unfairly discriminated against.

Reader i am so wise has little sympathy:

One of the components of freedom is the right to accept the consequences of one’s actions. If your idiocy makes your child a potential Typhoid Mary, well expect people to avoid you like the plague.

In Nature, Nurture and Switched Babies, Jonah of The Frontal Cortex relates an interesting case in which two baby girls were swapped in the hospital and given to the wrong families. When they turned into adults, both girls’ personalities were remarkably similar to their birth families—not the ones they were raised in. Though Jonah calls the Nature vs. Nurture debate a “false dichotomy,” the story does serve as a reminder that genetics play an immeasurable role in shaping who we become.

Reader Rachael found the story inspiring:

Stories like this are humbling for so many reasons. First, “I think I’ve got problems”, ha : ) Second, we know so little. I do not believe in a creator, but I am humbled by the complexity of these processes which we’d like to think we understand. I would be very bored and very sad if the day ever came that interesting occurrences like this were predictable.
