Decision-making is an essential part of life, whether personally or professionally. However, time pressure, lack of clear information or subjectivity can often make decisions difficult and even harmful. In this context, it is essential to have several opinions before making a final decision.

The importance of having several opinions when making decisions is based on studies of psychology and the brain. These studies show that the human brain is susceptible to cognitive views, that is, it tends to make decisions based on limited and subjective information, rather than objective and accurate information. Furthermore, these biases can be exacerbated in stressful or pressured situations, which can further impair decision making.

On the other hand, having multiple opinions can help avoid these cognitive views and ensure that the final decision is based on a more comprehensive and objective analysis. When you have multiple opinions, you can gain different perspectives on the same situation, which can lead to a more complete understanding of the issue at hand. This can lead to a better controlled and balanced decision.

Additionally, having multiple opinions can help reduce the impact of subjectivity on decision making. When you only have one opinion, the tendency is to follow that opinion without question. However, when you have several opinions, it is possible to evaluate these opinions critically and identify common points or divergences that can lead to a more objective decision.

Studies also show that diversity of opinions can lead to more creative and innovative decision-making. When you have people with different perspectives and experiences, you can generate more fun and creative ideas, which can lead to more innovative and effective solutions.
However, it is important to highlight that having different opinions does not mean making decisions out of companionship. It is essential that the final decision is made by a responsible person or group, who takes into account all available opinions and information. This can help ensure that the final decision is coherent and responsible.

In summary, the importance of having several opinions when making decisions is based on psychology and brain studies, which show that diversity of perspectives can lead to a more balanced, creative and innovative decision. Therefore, it is essential to seek the opinion of different people before making an important decision.
