The association between productivity and impact of scientific production is a long-standing debate in science that remains controversial and poorly understood. Here we present a large-scale analysis of the association between yearly publication numbers and average journal-impact metrics for the Brazilian scientific elite. We find this association to be discipline-specific, career-age dependent, and similar among researchers with outlier and non-outlier performance. Outlier researchers either outperform in productivity or journal prestige, but they rarely do so in both categories. Non-outliers also follow this trend and display negative correlations between productivity and journal prestige but with discipline-dependent intensity. Our research indicates that academics are averse to simultaneous changes in their productivity and journal-prestige levels over consecutive career years. We also find that career patterns concerning productivity and journal prestige are discipline-specific, having in common a raise of productivity with career age for most disciplines and a higher chance of outperforming in journal impact during early career stages.

跨学科和职业年龄的生产力和期刊影响之间的关联

生产力与科学生产的影响之间的联系是科学界的一个长期争论，至今仍存在争议且知之甚少。在这里，我们对巴西科学精英的年度出版物数量与平均期刊影响指标之间的关联进行了大规模分析。我们发现这种关联是特定于学科的，取决于职业年龄，并且在具有异常表现和非异常表现的研究人员中相似。离群研究人员要么在生产力或期刊声望方面表现出色，但他们很少在这两个方面都做到这一点。非异常值也遵循这一趋势，在生产力和期刊声望之间呈现负相关，但具有学科依赖性。我们的研究表明，学者们反对在连续的职业生涯中同时改变他们的生产力和期刊声望水平。我们还发现，与生产力和期刊声望有关的职业模式是特定于学科的，共同点是大多数学科的生产力随着职业年龄的增长而提高，并且在职业生涯早期阶段在期刊影响方面表现出色的机会更高。
