# Proactionary Principle The proactionary principle exists as a response to the precautionary principle, a rule of thumb often used when deciding whether to allow the pursuit of a technology that might have a negative consequence. In practice, the precautionary principle is strongly biased against technological progress, stating that "we should permit no new technology to be developed and no new productive activity to take place unless we can scientifically prove that no harm to health or environment will result." Alternatively, the proactionary principle emphasizes technological progress and our freedom to innovate and experiment, while also considering lost costs, payoffs and negative effects. The burden of proof against developing a new technology instead belongs to those who propose restrictive measures. People's freedom to innovate technologically is highly valuable, even critical, to humanity. This implies a range of responsibilities for those considering whether and how to restrict new technologies. Assess risks and opportunities using an objective, open, and comprehensive, yet simple decision process based on science rather than collective emotional reactions. Account for the costs of restrictions and lost opportunities as fully as direct effects. Favor measures that are proportionate to the probability and magnitude of impacts, and that have the highest payoff relative to their costs. Give a high priority to people's freedom to learn, innovate, and advance. [Read more..](http://www.maxmore.com/proactionary.html)
