The problems with this kind of interaction are quite obvious: The reason is that it is predictable and more or less error-proof: The user knows that the action has been requested from the server (the disabled state of the button hints at this), and once the server responds, the updated page clearly indicates the end of this client-server-client interaction. This might look quite inefficient in 2016 however, surprisingly enough, the same scenario is still used in a lot of web pages and applications and is still a part of the interaction process for many products. In the old days, interfaces were nowhere nearly as optimistic. ![]() The page is reloaded to reflect the status of the response.A response from the server is sent back to the page.The button is triggered into a disabled state.An interaction with a button, for example, could follow a scenario similar to the following: And the vast majority of them had not even a hint of optimism.

In this article, we will find out what concepts it is based on, and we will look at some examples as well as review its psychological background. Frankly, the term itself is not even well defined. Recently, having discussed psychological performance optimization at a number of conferences dedicated to both front-end development and UX, I was surprised to see how little the topic of optimistic UI design is addressed in the community. Have you heard of this third one? It is called an “optimistic UI.” Optimistic UI design is not about looking at the web through rose-colored glasses - at least not only about it. The third UI exits the pub already drunk immediately after going in - it knows how the pubs work and is efficient enough not to lose time. The second UI orders a drink, pays for it up front, orders another drink, pays for it and so on, and in a couple of hours leaves the pub drunk.
