Plural of desensitization; processes of making someone less sensitive, reactive, or responsive to something.
From de- (remove) + sensitize (make sensitive) + -ation (noun suffix). This term comes from psychology and neuroscience, used since the mid-20th century to describe therapeutic techniques and natural processes.
Desensitization is actually a helpful therapy technique—if you're terrified of spiders, a psychologist might use 'systematic desensitization' where you gradually encounter spiders in safer ways until your fear response weakens, proven to work better than just ignoring your fears.
