illogical
Without valid reasoning
Illogical describes reasoning or actions that violate logic—conclusions that don't follow from premises, or behavior that contradicts common sense: It's illogical to expect different results from the same approach.
The word often carries mild exasperation: Her fear of flying is completely illogical, but she can't shake it.
