Causal sequences can be segmented into cause and effect. However, some argue causal relations in discourse are by default in "effect-cause" order. Others claim "cause-effect" order is easier to process and the default way of expressing causality, due to iconicity. We conducted experiments testing participants' production choices in two different contexts--narratives and safety/warning signs--to see whether genres/discourse types differ in their preferred cause-effect order. We find that while narratives (which involve temporally anchored events) elicit iconic cause-effect order, safety signs (with generic statements rather than specific temporally anchored events) show a bias toward effect-cause. The present work highlights the importance of differences in text type and communicative purpose and suggests that there is no single answer regarding the primacy/salience of cause versus effect.
