<jats:title>Abstract</jats:title><jats:p>We show that both Rado's Conjecture and strong Chang's Conjecture imply that there are no special ℵ<jats:sub>2</jats:sub>‐Aronszajn trees if the Continuum Hypothesis fails. We give similar result for trees of higher heights and we also investigate the influence of Rado's Conjecture on square sequences.</jats:p>
