Democracy is a system of government in which power is vested in the people, who exercise it directly or through elected representatives. It is widely believed that democracy improves the quality of decision-making due to several reasons.

Decisions are taken by educated people:
In a democratic system, decisions are made by people who have been elected by the citizens. These elected officials are usually educated individuals who have a good understanding of the issues at hand. They have the knowledge and expertise to analyze complex problems, consider various perspectives, and make informed decisions. Their education enables them to critically evaluate the available information and propose solutions that best serve the interests of the people.

Decisions are taken by consultation and discussion:
Another reason why democracy improves decision-making is the emphasis on consultation and discussion. In a democratic system, decisions are not made unilaterally by a single individual or a small group. Instead, they are made through a process of deliberation and debate, where diverse opinions and viewpoints are considered. This ensures that decisions are not hasty or biased but are based on a thorough examination of all available options. Through open dialogue and debate, different ideas and perspectives are brought to the table, leading to more well-rounded and inclusive decisions.

Decisions are taken over a long period of time:
Democracy also allows decisions to be made over a longer period of time. Unlike authoritarian systems where decisions can be imposed quickly and without proper scrutiny, democratic decision-making involves a more gradual and deliberative process. This allows for a more comprehensive analysis of the pros and cons of different options, ensuring that decisions are well-thought-out and based on careful consideration.

All decisions are approved by the judiciary:
While the statement that all decisions are approved by the judiciary is not entirely accurate, it is true that the judiciary plays a crucial role in upholding democratic principles and ensuring the legality and fairness of decisions. In a democracy, the judiciary acts as a check and balance on the power of the executive and legislative branches of government. It ensures that decisions are in line with the constitution and protects the rights and freedoms of individuals. By providing an impartial and independent review of decisions, the judiciary helps to maintain the integrity and quality of decision-making in a democratic system.

In conclusion, democracy improves the quality of decision-making through the involvement of educated individuals, the emphasis on consultation and discussion, the consideration of different perspectives over a longer period of time, and the role of the judiciary in safeguarding the legality and fairness of decisions. These factors collectively contribute to more informed, inclusive, and well-thought-out decisions in a democratic society.
