Neither numerology nor the Chinese Zodiac is supported by scientific evidence and are widely regarded as pseudosciences.

Despite their widespread cultural influence and personal appeal, both numerology and the Chinese Zodiac lack empirical support and are not recognized as valid scientific disciplines. The claims made by these systems — that numbers or birth years can dictate personality, predict future events, or influence compatibility — have not been substantiated through rigorous scientific methodology, peer-reviewed research, or replicable experiments. Skeptical inquiries often point to the Barnum effect (the tendency for individuals to accept vague, generalized personality descriptions as highly accurate for themselves), confirmation bias (the tendency to seek out and interpret information in a way that confirms one's preconceptions), and the lack of falsifiability as reasons for their classification as pseudosciences. While they may offer psychological comfort or cultural connection, their predictive or explanatory power remains unproven by scientific standards.
