Whether writing a proposal, making a fundamental architecture decision, or selecting the right tools and libraries - in IT, we make risky decisions under uncertainty every day. We speak of decisions under uncertainty when we as decision-makers can only know and predict the state of the environment and possible consequences of the decision with uncertainty. Risk and trade-off analyses, many meetings and experts help us to minimize uncertainty and keep the risks within limits. Sometimes this does not go so well.

Despite rational circumstances, analyses and experts, our daily decisions are often subject to time and budget constraints. Every decision we make has consequences. The consequences of a decision are not always desirable. That is why it is important to make decisions under uncertainty, to know strategies and to prevent fallacies. This talk is about the psychology behind decisions under uncertainty.

How do people deal with risks, the probability of damage and loss? To what extent do character traits, emotions, age, experience, and external influences influence decisions under uncertainty? What role do statistics and perceived personal and economic consequences play in such decisions? We will look at paradoxes, theories, and strategies

from the field of decision theory under ambiguity and present well-known studies and solution strategies - always in relation to decisions from everyday
developer life.
