--- abstract: 'This chapter considers various factors that have been responsible for the comparatively slow development of psychology into a cumulative empirical science. Special attention is devoted to correctable methodological mistakes, the over-reliance upon significance testing (and the fact that, in psychology, the null hypothesis is almost always false), and an analysis of the concept of replication.' altloc: [] chapter: 1 commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Lykken given: David T. honourific: '' lineage: '' date: 1991 date_type: published datestamp: 1998-12-14 department: ~ dir: disk0/00/00/03/71 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Chiccetti given: D. honourific: '' lineage: '' - family: Grove given: W. honourific: '' lineage: '' eprint_status: archive eprintid: 371 fileinfo: /style/images/fileicons/application_pdf.png;/371/3/148.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'Philosophy of Psychology, significance testing, types ofreplication, null hypothesis' lastmod: 2011-03-11 08:53:51 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: 3-39 pubdom: FALSE publication: 'Thinking Clearly About Psychology, Vol. 1' publisher: University of Minnesota Press refereed: FALSE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 16:27:03 subjects: - phil-mind - phil-sci succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: "What's wrong with Psychology, anyway?" type: bookchapter userid: 101 volume: ~
