What does HBI mean in UNCLASSIFIED

The Harvey Bradshaw Index (HBI) is a measure of the perceived attractiveness of a person's face. It was developed by psychologists Harvey and Bradshaw in 1973 and is still widely used today. The HBI is calculated by taking an average of the ratings of a person's face on a scale of 1 to 7, where 1 is considered the least attractive and 7 is considered the most attractive.

The HBI is used in a variety of research studies on the psychology of attractiveness. It has been shown to be a reliable and valid measure of facial attractiveness and has been used to study the effects of various factors on attractiveness, such as symmetry, averageness, and cultural preferences.

The HBI is calculated by taking an average of the ratings of a person's face on a scale of 1 to 7. The ratings are typically made by a group of trained raters who are asked to judge the attractiveness of the face based on a set of criteria. The criteria used to rate attractiveness can vary depending on the study, but they typically include factors such as symmetry, averageness, and cultural preferences.

The HBI is a reliable and valid measure of facial attractiveness. However, it is important to note that the HBI is based on the ratings of a group of raters, and these ratings can be subjective. Additionally, the HBI does not take into account other factors that can affect attractiveness, such as personality and social context.

There are a number of things you can do to improve your HBI. Some of the most common suggestions include:

• Improving your skin care routine
• Wearing makeup that enhances your features
• Getting a haircut that suits your face shape
• Maintaining a healthy weight
• Exercising regularly
• Eating a healthy diet
• Getting enough sleep
• Reducing stress
• Smiling more often
