It's impossible to pinpoint a specific percentage of people who are "highly intelligent."
Intelligence is complex and multifaceted, with various definitions and measurement tools. There isn't a universally accepted standard for what constitutes "high intelligence."
IQ tests, while commonly used, are just one measure, and their results can be influenced by factors like cultural background and test-taking skills.
Furthermore, intelligence is not just about cognitive ability but also encompasses emotional intelligence, creativity, and practical skills.
Therefore, it's more meaningful to focus on individual strengths and talents rather than trying to label people based on a percentage.
