Final answer:
Those complicit in fraud often include unknowledgeable colleagues, powerful individuals, and authority figures who escape severe punishment due to their status and the incentives that shape their actions.
Step-by-step explanation:
In cases of fraud, often those implicated as at least complicit include co-authors or colleagues who fail to spot irregularities due to a lack of knowledge in statistical analysis and excessive trust; powerful individuals who leverage their international power to evade punishment; and professionals in positions of authority, like CEOs, who are not held criminally responsible despite their actions affecting thousands of victims. Furthermore, the prisoner's dilemma elucidates how individual incentives lead to suboptimal outcomes for all parties concerning accusations and trust.
