The Scientific Hypothesis Today

Author(s):  
Bradley E. Alger

Chapter 2 begins by reviewing the concept of the Scientific Method, as well as many outdated definitions of “hypothesis.” The discussion leads to the modern definition of the hypothesis as a conjectural explanation for a phenomenon; it is testable and falsifiable. The hypothesis serves as a blueprint and a summary of an investigation. Certain criticisms of the hypothesis and hypothesis-driven research are based on the older definitions of the term, and the book returns to them later. This chapter identifies and defines, with simple, nontechnical examples, concepts associated with the hypothesis, such as prediction and direct and indirect measurements. The philosophical programs of Karl Popper and John Platt, Critical Rationalism and Strong Inference, respectively, form a major focus of the chapter. The chapter explores the complexities of the concepts of falsification and corroboration and the importance of having multiple hypotheses. The chapter introduces the idea of the implicit hypothesis and ends with the presentation and discussion of key features of a good hypothesis.

Abstract. As the criticism of the definition of the phenotype (i.e., clinical diagnosis) represents the major focus of the Research Domain Criteria (RDoC) initiative, it is somewhat surprising that discussions have not yet focused more on specific conceptual and procedural considerations of the suggested RDoC constructs, sub-constructs, and associated paradigms. We argue that we need more precise thinking as well as a conceptual and methodological discussion of RDoC domains and constructs, their interrelationships as well as their experimental operationalization and nomenclature. The present work is intended to start such a debate using fear conditioning as an example. Thereby, we aim to provide thought-provoking impulses on the role of fear conditioning in the age of RDoC as well as conceptual and methodological considerations and suggestions to guide RDoC-based fear conditioning research in the future.

The Scientific Method Is Utilized In Order To Understand The Relationship Among Observations Of Physical Phenomena, While Minimizing The Influence Of Human Bias And Maximizing Objectivity. Specific Procedures For The Application Of The Scientific Method Vary From One Field Of Science To Another, But The Investigative Technique Universally Provides For An Analytical Framework To Acquire, Collect And/Or Integrate Knowledge. Engineering Forensics Involves The Analysis Of The Parameters Or Cause(S) Of Incidents Or Failures And/Or Hypothetical Prevention Methods. Engineering Analysis Of Forensic Problems Is A Multifaceted, Multidisciplinary Pursuit That Is Often Wide In Scope. Forensic Engineering Generally Applies Existing Science In Conjunction With The Knowledge, Education, Experience, Training And Skill Of The Practitioner To Seek Solution(S). The Scientific Method, Including Definition Of A Null Hypothesis, Is Rarely Utilized In Forensics As New Science Is Rarely Required. A Forensic Engineering Investigation Typically Involves The Application Of Long Established Science (Newtons Laws, For Example). Forensic Engineering Encompasses The Systematic Search For Knowledge Necessitating The Observation And Definition Of A Problem; The Collection Of Data Through Observation, Research, Experimentation And/Or Calculation; The Analysis Of Data; And The Development And Evaluation Of Findings And Opinions. The Ultimate Objective Of A Forensic Engineering Investigation Is Uncompromised Data Collection And Systematically Considered, Iteratively Derived And Objectively Balanced Conclusions.

Ion solvation and ion association are key features of ion-solvent interactions, and their balance largely determines structure, thermodynamics, and dynamics of electrolyte solutions. Despite being studied for many years with various techniques, these effects are still intriguing because too often results obtained with different methods-each having its individual merits and limitations-cannot be connected properly due to lacking information. In this contribution, we would like to bring dielectric relaxation spectroscopy (DRS) as a further tool for solution studies to the attention of the audience. The principles of DRS and the required instrumentation are briefly introduced. The major focus will be on the kind of results obtained with this technique regarding ion solvation and association and how this information compares with results obtained from other techniques.

This article examines the basis for testing historical claims and proffers the observation that the historical method is akin to the scientific method in that it utilizes critical elimination rather than justification. Building on the critical rationalism of Karl Popper – and specifically the deductive component of the scientific method called falsification – I examine his tetradic schema and adapt it for the specific purpose of historical analysis by making explicit a discrete step of critical testing, even though the schema is adequate as Popper expresses it and the elimination of error occurs at all steps of analysis. I also add a discrete step of critical elimination to Popper’s schema even though the elimination of error occurs at every step of analysis. The basis for critical elimination history is the demonstrable counterexample. The study of history will never approach the precision of science – history deals with open systems that cannot be replicated like experiments guided by fundamental laws. But just because we cannot know something with the rigor of science does not mean that we cannon know it better than we do. There may be no objective truth in an absolute sense, but there is a distinction to be made between well-tested and poorly tested theories and therefore between history done well and history done with less analytical rigor. What I hope to show is how our historical knowledge may progress through good faith critical discussion – history is discussion – and the elimination of error.

Abstract This paper aims at making a synthesis of the main discursive schemes at work across Western liberal democracies that have sought to legitimize the introduction of liberty-restricting counter-terrorism policies since the September 11th attacks. Redefinition of the nature of threat, of the attackers’ key features and of endangered values has gone along with the conceptual reversal of the definition of democracy and freedom as political value. The normalization of the ensuing illiberal forms of governance arguably suggests that the shrinking of post-war democratic achievement uncovers above all liberal democracy’s inherent political vulnerability.

This chapter considers four of the most influential visions that characterized the response to totalitarianism, and in particular the various concepts of limit they provide, since those are the basis of the opposition which each vision sought to oppose to the totalitarian ideal. The first vision is the positivist one of Karl Popper, for whom the logic of scientific method offers the only genuine knowledge of man and society. The second great vision is that of Berlin, who abandons positivism and instead presents the human condition in tragic terms, on the grounds that it is intrinsically characterized by a plurality of incommensurable and conflicting values. A third vision situates positivism in a naturalistic portrait of the human condition. Finally, there is the ‘civil’ vision of Michael Oakeshott, which is ultimately grounded in a radical, anti-reductionist conception of human freedom.

This chapter starts with a definition of the term ‘referendum’. A referendum is a means of involving the public in political decisions via voting on specific issues such as leaving the European Union. The chapter focuses on the use of referendums at the local level. It sets out the key features of a referendum. Who is allowed to vote in referendums? What sort of questions are put to voters? Under want circumstances should a referendum take place on specific issues? What are the risks associated with holding a referendum? The chapter also looks at regulations surrounding referendums in the UK. The theoretical considerations that the chapter examines are the fact that a referendum subject tends to be controversial, the relationship between referendums and direct democracy and the implications of the results.
