Attention has to compete
Selective attention and inhibitory control help keep irrelevant information from dominating the task at hand. When interference is high, identifying a priority can become much more difficult.
Lantern represents access to the cognitive functions that help a person hold information in mind, filter interference, shift perspective, and decide what deserves attention. Clarity here means usable mental organization—not perfect certainty.
Executive-function research consistently identifies working memory, inhibitory control, and cognitive flexibility as core processes that support reasoning and goal-directed behavior. These processes are also sensitive to stress, which helps explain why the same problem can feel manageable one day and mentally impenetrable another.
Selective attention and inhibitory control help keep irrelevant information from dominating the task at hand. When interference is high, identifying a priority can become much more difficult.
Working memory supports keeping relevant information active while comparing options, reasoning, or completing multi-step thinking. When it is overloaded, even familiar decisions can feel confusing.
Cognitive flexibility supports shifting viewpoints and adapting when new information appears. Acute stress can reduce prefrontal efficiency, making flexible, reflective thinking harder to access.

Lantern does not require a person to know the final answer. It describes having enough cognitive room to distinguish what is known from what is assumed, hold a manageable amount of information in mind, and see at least one relevant priority.
