Able to be confuted or refuted; capable of being proved wrong or disproved by argument.
From confute (Latin confutare, to beat down, refute, from con- + futare) + -able (capable of being). The Latin futare meant to thrust or strike, so confutare literally means 'to strike against.'
Every confutable claim needs someone willing to confute it—this is why peer review in science works, because scientists make careers out of finding and disproving weak arguments, creating a system where only the strongest ideas survive.
