Abstract：
In this article, we introduce some simple models, based on rolling dice, to explore mechanisms proposed to explain planetary habitability. The idea is to study these selection mechanisms in an analytically tractable setting, isolating their consequences from other details which can confound or obscure their effect in more realistic models. We find that the observable of interest, the face value shown on the die, \"improves\" over time in all models. For two of the more popular ideas, Selection by Survival and Sequential Selection, this is down to sampling effects. A modified version of Sequential Selection, Sequential Selection with Memory, implies a statistical tendency for systems to improve over time. We discuss the implications of this and its relationship to the ideas of the \"Inhabitance Paradox\" and the \"Gaian bottleneck.\"
摘要：
在这篇文章中,我们介绍一些简单的模型，基于滚动骰子，探索解释行星可居住性的机制。这个想法是在一个易于分析的环境中研究这些选择机制，将它们的后果与其他细节隔离开来，这些细节可能会混淆或模糊它们在更现实的模型中的效果。我们发现可观察到的兴趣，模具上显示的面值，随着时间的推移，“改进”在所有模型中。对于两个更受欢迎的想法，生存选择和顺序选择，这取决于采样效应。顺序选择的修改版本，带记忆的顺序选择，意味着系统随着时间的推移而改善的统计趋势。我们讨论了这一点的含义及其与“居住悖论”和“盖亚瓶颈”思想的关系。\"
