The article explores how the precision of advice affects how likely people are to follow it. The researchers conducted a study with 195 participants to see if more precise advice led to better decision-making. They found that when advice was more precise, people were more likely to take it. This suggests that the quality of advice can be judged based on how precise it is. The study showed that advice precision influences decision-making by signaling its quality, ultimately affecting how likely people are to follow it.
