Each of these tales has been around for centuries, and each has a fun rationale — higher heart rates supposedly mean girls, sweet cravings supposedly mean girls, and so on. Researchers who have tested them find accuracy indistinguishable from chance. That's exactly why our quiz labels its result as a "lean" and reminds you: only an ultrasound (or the birth itself!) is definitive.
每条传说都流传了数百年，也都有好玩的理由——据说胎心快是女孩、爱吃甜是女孩，等等。研究人员测试后发现其准确率与随机无异。这正是本测验把结果称为"倾向"的原因，并提醒你：只有超声（或出生本身！）才是确定的。
