German builds two different verbs on trauen, to trust.
jemandem vertrauen
To trust someone.
jemandem etwas zutrauen
To believe that someone is able to do something.
Traust du dir diese Aufgabe zu?
Do you think you can handle this task?
das Zutrauen
Confidence in someone’s abilities.
Opinion polls use the second verb to ask about competence. In the ARD-DeutschlandTrend of September 2021 the question was: Welcher Partei trauen Sie am ehesten zu, die wichtigsten Probleme in Deutschland zu lösen? Which party do you think is most able to solve the most important problems in Germany? The statistics portal Statista files the answers under the party with the greatest competence.
