Which term describes actions that are hasty and lack attention to detail?

The term that aptly describes actions that are hasty and lack attention to detail is "perfunctory." This word is often used to characterize tasks or duties performed with minimal effort or thought, indicating a cursory or superficial approach. When one engages in perfunctory actions, the emphasis is on completing the task rather than executing it with care or thoroughness, which directly aligns with the description of being hasty and lacking detailed attention.

In contrast, the other terms provided do not convey this meaning. "Veneration" refers to a deep respect or reverence for someone or something, which has no relation to the quality of hasty actions. "Dolorous" denotes a sense of sorrow or grief, not the manner in which tasks are executed. "Consummate" describes something that is complete or to the highest degree, often involving skill or excellence, which is the opposite of a hasty and careless approach. Hence, "perfunctory" is the most fitting choice for actions that lack detail and are done quickly without care.
