Plural form: multiple instances of lack of belief, rejection of faith, or refusal to accept something as true.
From dis- + belief (from Old English belefe, 'to believe'). The plural form is relatively uncommon since disbelief is often used as an uncountable noun.
Disbeliefs in the plural is rare because we usually treat disbelief as a single state of mind, making the plural grammatically possible but psychologically odd.
