Subjectivization can make things seem less certain or more open to different ideas.
Examples:

I don't like the subjectivization of science. I want to know what's really true.
The subjectivization of history can make it hard to know what really happened.
The subjectivization of cake recipes is a serious matter!
The subjectivization of the weather report made it seem like anything could happen.
The subjectivization of the rules made it hard to know what to do.
