Which types of attitudes are the strongest and the most resistant to change?

A) attitudes that are adopted from others
B) attitudes that are attained vicariously
C) attitudes that are observed in others
D) attitudes that are formed through direct experience

Attitudes that are formed through direct experience tend to be the strongest and most resistant to change because they are rooted in personal firsthand experience, which provides individuals with a sense of confidence and certainty in their beliefs. This type of attitude is likely to be reinforced over time, making it even more resistant to change. Attitudes that are adopted from others, attained vicariously, or observed in others may be more easily swayed or influenced by external factors such as new information or social pressure.
