The rarest enneagram 7 combination; SP/SX 7

 Self-Preservation Seven (SP/SX) subtype is generally considered the rarest among Enneagram Type Seven subtypes. While Self-Preservation types are typically the most common overall, SP-dom 7s are an exception, with the majority of Sevens being either Social or Sexual first. This is because the Self-Preservation instinct, focused on security and practicality, often clashes with the core desires of a Type Seven, who are typically adventurous and future-oriented. 

Here's a more detailed explanation:

Self-Preservation (SP) Instinct: This instinct focuses on physical survival, comfort, and security. 

Sexual (SX) Instinct: This instinct focuses on intensity, passion, and merging with another person or ideal. 

Social (SO) Instinct: This instinct focuses on belonging, social interaction, and fitting in. 

Therefore, sp/sx 7s are one of the rarest types and the least numerous subtype of type e7 In the context of Enneagram Type Seven, which is known for its love of adventure, variety, and optimism, the Self-Preservation instinct can create a countertype dynamic. SP 7s may appear less stereotypically "Seven-like" due to their focus on practical matters and security, which can lead to a more grounded and less outwardly enthusiastic presentation compared to other 7 subtypes. SX7s are more abundant than you think.

While according to a Reddit thread, Self-Preservation dom is the most common type overall, SP 7s are an exception within the Type Seven personality. This makes SP/SX 7s, with their combination of SP and SX instincts, a rarer subtype.
