Ensuring unpredictability in reinforcement is crucial for the success of implementing variable ratios because it creates a scenario where the subject does not know when the next reward will come. This uncertainty encourages persistent behavior, as the individual keeps engaging in the desired action in anticipation of the next reward. In the context of behavioral psychology, this unpredictability is what makes variable ratio schedules particularly effective for maintaining high levels of engagement and motivation.

For example, when a person is rewarded for a behavior on a variable ratio schedule—such as a slot machine payout that is unpredictable—they are likely to continue trying, even when they don’t win immediately. The excitement and uncertainty of not knowing when a reward will occur keep them engaged.

While a high frequency of rewards can be beneficial, it does not capture the essence of variable ratios, which rely on the unpredictability of reinforcement. Frequently changing the type of reinforcement can cause confusion and undermine the effectiveness of the reinforcement schedule, while reducing all forms of reinforcement would likely lead to decreased motivation and engagement, which betrays the intent of using a variable ratio approach. Hence, maintaining that element of unpredictability is vital for fostering a sustained response to the behaviors being reinforced.
