ts not about lacking integrity, its about being able to keep some things private when you don't want others to know.
There are ways of doing that without lying. Change the subject? Say, "I'm not really comfortable talking about this." Maybe not as easy as just glibly telling a lie, but some people just can't live with themselves if they're dishonest. It's a personal choice.
Would you say the same of a woman who was newly pregnant? If asked outright if she was expecting she said no.
Yes, I would. If she lied, yes. It's quite black and white.
Is her desire to keep some things private because she has personal reasons for not sharing them when asked more or less important that your right to know?
My imaginary but integrity-packed pregnant woman would say, "Mind your own business, you nosy cow!" Or admit that she's not comfortable talking about this subject, or say that she wouldn't announce a pregnancy until the 12-week scan, or any number of things that aren't just a blatant lie.
Would you say she lacked integrity?
If you lie, you lack integrity. The definition of integrity:
Integrity is the quality of being honest and having strong moral principles, or moral uprightness. It is a personal choice to hold one's self to consistent standards. In ethics, integrity is regarded as the honesty and truthfulness or accuracy of one's actions.
So yes, our fictional pregnant fibber lacks integrity if she tells a lie.
You're implying that lying isn't lying if you have a valid reason for lying.
