Bad is stronger than good. Negative information will attract our attention more than positive information will.
When deciding on what information is presented to users of your system, consider the fact that negative information or design elements with a negative tone will ring more attention than positive information and design will.
You can utilize this fact in your design by paying great attention to what negative feedback is presented to the user. Is it really important? Does it bring the users closer to their goal(s)? If you want users to pay attention to positive information, be careful not to let negative feedback outshine the positive.
