"El mero hecho de que la izquierda parece no tener alternativa a sus políticas fallidas aparte de la noción de que, dado que la gente no fue persuadida por sus argumentos, esos argumentos deben repetirse en voz más alta sugiere una disonancia cognitiva que "

Simplified Meaning:

Sometimes when people have an idea or plan that doesn't work, they don't come up with a new plan. Instead, they just keep repeating the same thing more loudly, thinking maybe others will agree if they shout louder. This behavior shows that they are not recognizing or accepting that their idea is flawed. They are ignoring the reality that their plan is failing and just trying harder with the same approach. For example, imagine a salesperson who is trying to sell a product that nobody wants. Instead of improving the product or changing the sales strategy, they just start yelling about it, hoping people will buy it because of the noise. In life, when faced with failure, it is important to rethink our strategy and not just insist louder on the same failing point. Being open to change and listening to feedback can help us find a better solution.
