Brainlessly is an adverb meaning that an action is performed without thought, intelligence, or careful consideration. It often describes a person agreeing, following instructions, making a decision, or responding to circumstances without examining them. The word generally carries a critical or mildly humorous tone: calling an action brainlessly suggests that it is foolish, uncritical, or based on a lack of judgment. Its force can become stronger when it describes behavior in a group, such as people brainlessly following a trend or accepting a dubious claim. Brainlessly is the adverb derived from the adjective brainless. Although it may sound informal, it is widely understood in both British and American English and is especially useful when the manner of an action, rather than the intelligence of the person performing it, is the main point of criticism.

Brainlessly is an English adverb formed by adding the suffix -ly to the adjective brainless. Brainless combines brain with the suffix -less, and brain derives from Old English brægen, meaning the brain or understanding. The productive -ly suffix converts many adjectives into adverbs describing manner, so brainless came to yield brainlessly with the meaning of acting in a brainless manner.
