Previous works determined a characterization of logically consistent statistical hypothesis tests and showed that the modal operators obtained from this test can be represented in the hexagon of oppositions. However, despite the importance of precise hypothesis in science, they cannot be accepted by logically consistent tests. Here, we show that this dilemma can be overcome by the use of pragmatic versions of precise hypotheses. These pragmatic versions allow a level of imprecision in the hypothesis that is small relative to other experimental conditions. The introduction of pragmatic hypotheses allows the evolution of scientific theories based on statistical hypothesis testing to be interpreted using the narratological structure of hexagonal spirals, as defined by Pierre Gallais.<\/jats:p>","DOI":"10.3390\/e21090883","type":"journal-article","created":{"date-parts":[[2019,9,11]],"date-time":"2019-09-11T11:26:34Z","timestamp":1568201194000},"page":"883","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Pragmatic Hypotheses in the Evolution of Science"],"prefix":"10.3390","volume":"21","author":[{"given":"Luis Gustavo","family":"Esteves","sequence":"first","affiliation":[{"name":"Instituto de Matem\u00e1tica e Estat\u00edstica, Universidade de S\u00e3o Paulo, S\u00e3o Paulo 05508-090, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0379-9690","authenticated-orcid":false,"given":"Rafael","family":"Izbicki","sequence":"additional","affiliation":[{"name":"Departamento de Estat\u00edstica, Universidade Federal de S\u00e3o Carlos, S\u00e3o Paulo 13565-905, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2720-3871","authenticated-orcid":false,"given":"Julio Michael","family":"Stern","sequence":"additional","affiliation":[{"name":"Instituto de Matem\u00e1tica e Estat\u00edstica, Universidade de S\u00e3o Paulo, S\u00e3o Paulo 05508-090, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4323-4515","authenticated-orcid":false,"given":"Rafael Bassi","family":"Stern","sequence":"additional","affiliation":[{"name":"Departamento de Estat\u00edstica, Universidade Federal de S\u00e3o Carlos, S\u00e3o Paulo 13565-905, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"732","DOI":"10.1093\/jigpal\/jzv027","article-title":"Logical consistency in simultaneous statistical test procedures","volume":"23","author":"Izbicki","year":"2015","journal-title":"Log.
