Such a statement is only wrong because of its incompleteness. Negative 
feedback reduces the overall gain of an amplifying circuit and 
compensates for distortion by cancelling out some of the input signal. 
If an amplifier circuit through design or implementation problems has 
end to end positive feedback, it can become unstable without negative 
feedback.

Negative feedback can only have a moderating effect if there is positive 
feedback in intermediate circuits within the amplifier chain. Under 
these circumstances it is not uncommon for the instability to move 
outside of the normal operating range. In audio amplifiers, this usually 
then manifests itself as distortion, because the amplifier is being 
fully driven producing RF.

Saying that negative feedback stabilises an amplifier is half an answer. 
The problem with half answers is that they can be more dangerous than no 
answer, because they can lull one into the belief that they have the answer.
