再给一个当红学者的例子：Lisa Feldman Barrett，President, Association for Psychological Science, 2019–2020。她说她曾经分不清love和flu：

One day at graduate school, one of Lisa Feldman Barrett's colleagues asked her out on a date. She didn't really fancy him, but she had been in the lab all day and felt like a change of scenery, so she agreed to go to the local coffee shop. As they chatted, however, she started to become flushed in the face, her stomach was churning, and her head seemed to whirl. Maybe she was wrong, she thought: perhaps she really did like him. By the time they left, she'd already agreed to go on a second date.

Still feeling somewhat giddy, she got home, put her keys on the floor, and promptly threw up. It wasn’t love, after all; it was flu. She spent the next week in bed.

这是不是有点问题？假作真时真亦假，心灵都分不清真假，研究和教育都分不清真假，比新冠病毒后果更严重的问题也很快会出现。
