The level of confidence you require may vary for different situations. For example, the level of confidence you need in your doctor is probably different than the level of confidence you need in the person designing the video games you play.

 

Level of confidence can be affected by a variety of factors. For instance, a video game company may require a higher level of confidence in the video game designers it hires than the average consumer requires. The company’s success is dependent to some degree on the ability of the video game creator to create interesting and fun games.

 

Another factor affecting level of confidence could be the company’s history. You would probably have more confidence in a bungee jumping company that has had over 10 000 successful jumps and a flawless safety record than a bungee jumping company where you are the first customer to jump.
