Scorpios tend to be fully committed in love, and all their tenderness and intelligence seem to exist only for lovers. They are cold in front of outsiders and don't put their time and energy on irrelevant people. However, in front of the person they like, they seem to have lost their IQ, and some things they would not have done would have been willingly done for the sake of their lovers. They always put all their passion and intelligence into their lovers, so much so that they appear to have a low IQ in love.
Taurus natives usually become very stubborn in love. They seek stability and security and have high expectations for their relationships. However, when they encounter true love, they are often too attached to see reality and even lose themselves. They may repeatedly give the other person reasons and excuses, even when they know that the other person does not really love them. This overly persistent attitude and behavior often leads to a low IQ in their relationship.
Libras tend to lose their balance easily in relationships. They place a high value on relationships and want to maintain a harmonious relationship with all. In a relationship, they may be so accommodating to each other that they ignore their own feelings and needs. They may be too perfectionist to see reality and even lose themselves. This loss of balance and rationality often leads to a low IQ in their relationships.
