Being misinformed due to the 'abstinence only' sex-ed. I wouldn't blame it on the teen, but on the education system, or the teen's parents who can't be bothered to teach birds and bees.

Misinformed how? It's not as if abstinence-only education claims babies come by stork.

It often claims things like condoms being ineffective against STDs or all sorts of birth control having far greater failure rates than in reality.

I was also taught: never carry a condom, because then you might be tempted to have sex. Instead of understanding that it's going to happen anyway, they teach that it shouldn't happen, so don't prepare for it.

Misinformed because they don't inform the kids about birth control. It's a sin of omission

Teens being denied access to proper and accurate sex education isn't their own doing.

I have significant shared frustration with that situation, but feel that even in those cases, the teens bear a non-zero amount of responsibility, which is larger than the baby.

Most teens can read and most have access to google.

>Most teens can read and most have access to google.

I can read and I have access to google, and for some reason I'm not a rocket scientist or a nuclear physicist. There is a reason that in most cases we don't consider (at least below 18) teens adults. They make bad decisions. We also know from study that teens make a higher number of bad decisions when the adults and culture around them feed them bad information.

Google is almost useless for things like this, your family and culture affect you far more.
