The main points suggest that in modern wars, under the dual influence of the raided party's own cognitive limitations and the other party's induction, once there is a cognitive bias, it is easy to go further along the wrong path: from cognitive limitations, cognitive bias, cognitive bias to cognitive paranoia, and finally when the truth is known, there will be cognitive confusion and fall into cognitive paralysis. While conducting cognitive surprise attack on the enemy, we should also prevent our own cognition from standing still because of the successful surprise attack, or even digging a "cognitive trap" without knowing it and being counterattacked by the opponent's cognition. The essence of surprise is surprise. Cognitive surprise refers to making use of the opponent's cognitive limitations and thinking patterns in the confrontation to create unexpected effects for the opponent, so as to achieve victory with ingenuity. Recognizing the internal mechanism and external effect of surprise attack implies the law of slow release and increase, and fully understanding and effectively utilizing this law is of great significance for winning the enemy in the future war. The scientific principle of clarifying the law of gradual increase in slow release The law of gradual increase in slow release of cognitive surprise refers to the slow release of the effect of cognitive surprise, and its impact increases with time. Compared with other forms of raids, cognitive raids have more special effects and more serious consequences. Once the surprise attack works, the impact on the enemy's cognition will not disappear or change in a short time due to the disclosure of their own real intentions, real actions and real information; On the contrary, the effect of surprise will increase over time. In the modern war, under the dual influence of the raided party's own cognitive limitations and the other party's induction, once there is a cognitive deviation, it is easy to go farther and farther along the wrong path: from cognitive limitations, cognitive deviations, cognitive bias to cognitive paranoia, and finally when the truth comes out, there will be cognitive confusion and cognitive paralysis. During this period, the raided party was not only hard to extricate itself, but also hard to know, and the misconception was solidified and deepened over time. The scientific principle for this rule to play its role lies in the inherent limitations of the human brain's mechanism of thinking about problems and processing information: the brain has a self-protection mechanism, subconsciously follows the principle of saving brainpower when dealing with complex problems, and processes information and knows the outside world through the internal "mental model". This mechanism shows that once a certain kind of cognition is formed, it will often produce cognitive inertia and path dependence, resulting in selection preference. When the thinking model in the brain filters and filters the external information, it tends to accept the information consistent with the existing cognition, and at the same time, it instinctively filters out the abnormal information, which deviates from the objective facts unconsciously. In the military field, this mechanism will produce a diffusion effect, extending from individual cognitive errors to collective cognitive errors. Once the cognition is formed, the decision-maker will tend to adopt the information and suggestions that conform to his/her own opinions and reject the opposing opinions, which is easy to form a "top atmosphere" and a mentality of conformity. Affected by this, all levels are more inclined to put forward information and suggestions that cater to superior decisions and public expectations, and even filter out abnormal information and objections at the expense of objectivity and authenticity. In this two-way interaction and feedback process, individual false cognition is transformed into collective false cognition and constantly strengthened, so that it is difficult to distinguish the true from the false, falling into the embarrassment of "true is also false when false is true". In the confrontation between the opposing parties, this rule is manifested in that once false cognition is formed, it will subconsciously classify and filter information,
