WebScikit-learn classifiers generally choose the predicted class by taking the argmax of scores/probabilities (see LogisticRegression and DecisionTreeClassifier). For binary classification problems, the argmax is equal to using a 0.5 threshold on probabilities. In this case, varying the threshold changes your confidence about the predicted classes.
