The problem with the focus group

If a recently published piece from the New York Times is to be believed, there is a contingent of reformed Trump supporters who regret voting for Trump. This conclusion was taken from a focus group of self-styled MAGA republicans who, for the most part, reported varying degrees of disappointment with Trump's second term.
Conservative disillusionment continues to be a popular narrative, perpetuated by
poll numbers barely clinging to the double digits and the heel-turn of Tucker Carlson, Candace Owens, and other once-loyal pundits. There are symptoms that the enterprising opinion writer can turn to bolster an argument for the president's crumbling network of support, but the focus group shouldn't be considered among them.
Consider the format. A group of men and women, supposedly chosen for their self-reported political inclinations. The focus group demands a level of credulity that wouldn't be suitable in more empirical studies.
Testers must also consider the impact individual participants might have on feedback from the group. A single outspoken member or perceived group consensus could easily sway individual responses.
