Final answer:
Accessible attitudes are more likely to predict spontaneous behaviors as they are easily retrievable from memory and align with the availability heuristic, affecting decision-making and perception of frequency in events.
Step-by-step explanation:
Highly accessible attitudes are more likely to predict spontaneous behaviors because they can be retrieved from memory quicker and with greater ease than less accessible attitudes. This accessibility often correlates with the frequency and recency of thoughts, linking with the availability heuristic, which describes our tendency to use immediate examples that come to mind when evaluating information or making decisions. For instance, stories of violent crime or terrorism are so vivid in media that individuals overestimate their frequency, proving that easily recalled information has considerable influence.
This phenomenon can also be connected to the actor-observer bias, where as observers, we have less information about others and are thus more likely to make dispositional attributions for their actions. However, when we're the actor, we have more context and are prone to attribute our behavior to situational factors. This is why accessible attitudes, which are part of our immediate conscious experience, strongly govern our spontaneous behaviors.
