No. Jain people are not irrational.

Jain Dharma is deeply grounded in reason, self-discipline, non-violence, and careful thinking. Important Jain principles like:

• Anekāntavāda — truth has multiple aspects
• Syādvāda — statements should be made with humility and context
• Ahimsa — non-violence in thought, speech, and action
• Aparigraha — non-possessiveness and restraint

all show a thoughtful and disciplined approach to life.

If someone behaves irrationally, that is an individual matter, not a trait of Jainism or Jain people as a whole. In Jain view, every soul has the capacity for wisdom, restraint, and right understanding.
