eHarmony, #1 Trusted Relationship site

Scientific Match Making

Out of all the single people you will meet in your life, only a very few would make a great relationship partner for you. Some singles aren't attractive to you. Others aren't ready for a relationship. Of the rest, many are great people who you might enjoy chemistry with initially, but they aren't compatible with you in the important ways that make long-term dating and relationships work. That's where eHarmony comes in. By combining the best scientific research with detailed profiling of every member, we screen thousands of single men and single women to bring you only the ones that have the potential to be truly right for you.

Based on his 35 years of marriage counseling and studies of thousands of married couples, eHarmony founder Dr. Neil Clark Warren exhaustively researched what makes marriages succeed and fail. His findings? Chemistry is not enough. Almost all marriages start out with good chemistry, yet 3 out of 4 couples end up unhappy or divorced.


By studying the difference between happy and unhappy married couples, Dr. Warren's team of researchers found 29 Dimensions® that help predict great relationships. These compatibility dimensions include:

  • Core traits like emotional temperament, adaptability, curiosity, and intellect
  • Values and beliefs, such as spirituality and feelings about children
  • Relationship skills, such as conflict resolution
