There was an experiment where a group of people were shown a video of two groups tossing basketballs to each other. One group wore white shirts, the other black, each with their own ball. The subjects had to count the number of passes between players in white shirts, given that the space was tight and players moved chaotically. The task was difficult because players moved quickly and the ball constantly passed from one team to another. If they concentrated, most subjects counted correctly. But the experiment was about something else. It turned out that in the middle of the video, a person in a gorilla suit walked onto the court, waved at the camera, and left (Video variant with a bear). He was on screen for several seconds. The subjects did not notice him. If they had no task to count passes, they noticed the gorilla. But those without the task had no idea how many passes the players made. The experiment was conducted on several thousand people, and the results were confirmed for all.

In my opinion, this experiment strongly supports two theses about startups. First, that you need to focus. Second, that a startup needs a team. Our brain works in such a way that we either look broadly and notice everything, but there will be no precision, ideas, breakthroughs, or we concentrate on a specific goal and miss everything around. A startup cannot afford to look around — it needs to be clearly, quickly, and precisely focused on one point, and a team allows distributing these goals and understanding everything around very well if knowledge is shared at weekly/daily goals. Therefore, we focus as a team, but each on their own.
